Attaching the label to the printer
1 A sheet of labels ships in the paper output bin of your printer. You will need to attach two labels to your printer: the first label is entitled Remove and Realign Paper Before Reloading," the second label is entitled, "Do Not Switch the Paper Path while Printing." 2 Carefully remove labels from the backing sheet. Attach labels to the printers paper input bin. As the label indicates, always remove and realign all paper before reloading. By doing so, you can reduce multiple paper feeds, paper jams, or both.
Attaching the label to the printer 13
Loading paper into the printer
1 Before loading paper into the printer, raise the paper supports located behind the paper input bin and the paper output bin. Using paper supports can help prevent unwanted paper curl and paper jams. 1 Raise the supports on the paper input bin and on the paper output bin until they snap into place. Insert up to 100 sheets of paper into the paper input bin.
Note Be careful not to overfill the bin. Center the paper using the paper guides on the paper input bin.
To test your printer, you can print a selftest page. To do so, make sure the Ready (bottom) light is on and all other indicator lights are off. Press and release the control panel button. (If the printer is in SleepMode [all lights are off], you will need to press the control panel button twice.) The Data (middle) light will come on and the Ready (bottom) light will blink. The self-test page prints. Note When adding paper to an existing stack in the paper input bin, always remove and realign all paper to avoid multiple paper feeds, paper jams, or both.

If you are printing only one piece of letterhead, use the single-sheet input slot. Note If youre having printing problems on embossed or pre-printed paper, make sure the paper meets HP paper specifications, see appendix C.
Printing on letterhead and envelopes 31
If you print one envelope followed by regular sheets of paper, place the envelope into the (A) single-sheet input slot and regular sheets of paper into the (B) paper input bin. If you are printing several envelopes in succession, fill the paper input bin (B) with up to 10 envelopes. The number of envelopes depends on envelope construction and the operating environment. If you are printing only one envelope, use the single-sheet input slot. Insert the envelopes print side forward as shown. Set the paper path lever to the lower position to reduce wrinkling and curling.
32 Chapter 3 - Printing
Your printer capabilities include duplex printing, pausing between pages, and stopping a print job. You can also reset your printer if necessary.
Printing on both sides (duplexing)
When you print on both sides of a sheet, you may notice a difference in the way the printer performs. When printing on the second side of the sheet, you may experience some difficulties, such as getting the sheet to feed into the printer or multiple feeds. In addition, the print quality may be different on the second side of the sheet. To minimize these problems, you will want to use paper meeting HP paper specifications in appendix C. 1 Print the first side of the sheet as you normally would. Some software programs include options that are useful when duplex printing, such as printing just the odd pages or the even pages." Consult your software user manual. Allow the sheet to cool and flatten before printing on the second side to get the best possible print quality. Print the second side by placing the sheet back into the paper input bin or the single-sheet input slot. Make sure the side that has already been printed is facing the back of the printer and the top edge of the paper is down, as illustrated below.
Printing tasks 33
Tips for duplex printing
To avoid paper curl, set the paper path lever to the lower position and use the heavy media output slot for a straight-through paper path. To print one page at a time, select the manual feed option in your software to pause the printer between pages. Make certain that the sheets leading edge is not bent or curled.
Pausing the printer between pages
Occasionally, you may need the printer to pause so that you can load special media, such as letterhead. If you specify manual feed in your software, the printer will pause before printing the first page and between each page you print. This will give you time to load the special media. In your softwares printer menu or bin/tray selection, select the manual feed mode. From your software, print the document. The Data light will blink when the page is ready to print, indicating that the printer is paused and waiting. After inserting the correct medium, the printer will pick the sheet automatically. The printer will take media from the single-sheet input slot first. If it does not find media in the single-sheet input slot, it will take media from the paper input bin.
Resetting the printer
Resetting the printer accomplishes the following:
Clears all data from the printer memory (including unprinted data, downloaded fonts, and macros). Finishes printing the current page. Removes some error conditions. Resets the printer to its factory default settings.
To reset the printer
Press and hold the control panel button until the three indicator lights begin to blink in succession (about 5 seconds), and then let go of the button. After resetting, the Ready light will remain lit if no printer errors are found.
34 Chapter 3 - Printing
Stopping a print job
If the file you send to the printer is only one or two pages long, you can stop the print job by resetting the printer as described above. If you want to stop a large print job, see the steps below: 3 Remove the media from the paper input bin except for any sheet that is currently being fed into the printer. Stop and delete the print job through your software. Reset the printer.
Printing tasks 35
Printing on special media
Your printer is designed to print on a variety of media, including transparencies, envelopes, and custom-made paper. It is recommended that you use media that meets HP specifications. See appendix C for more information. 1 Set the paper path lever to the lower position to use the heavy media output slot for a straight-through paper path. This is important when printing media such as postcards, transparencies, labels, envelopes, and heavy paper (100- to 157g/m2 [28- to 42-lb] bond weight). Adjust the paper guides to the approximate size of media you are using. Insert the media print side forward and top side down into the single-sheet input slot or the paper input bin. Readjust the paper guides to center the media. Set the correct margins, paper size, and orientation in your software. Choose Print in your software.
Additional tips for custom sizes
Do not print on media smaller than 76.2 mm (3 in) wide or 127 mm (5 in) tall. Set margins of at least 6.4 mm (.25 in) in your software. Always insert media lengthwise (vertically) into the printer. If you want to print in landscape mode, make this selection through your software.
36 Chapter 3 - Printing
Additional tips for transparencies
To prevent transparency curl, remove the transparency as it comes out of the printer and set it on a flat surface to cool. WARNING! Use only transparencies specified for HP LaserJet printers.
Additional tips for printing labels
Do not use labels that are separating from the backing sheet or that are wrinkled or damaged in any way. Do not use any sheet of labels that has spaces in it where some of the labels have been removed. Do not feed a sheet of labels through your printer more than once.
Solving common problem 41
Clearing paper jams
Occasionally, paper can become jammed while printing. The following list shows some possible causes:
q q q q
The paper was loaded improperly. The paper input bin was overfilled. The guides were not adjusted to the correct position. More paper was added without unloading the bin and realigning all media first. The paper output bin was too full. The paper path lever was adjusted while printing. The printer door was opened while printing. The paper being used does not meet HPs specifications. The paper being used was smaller than 76.2 by 127 mm (3 by 5 in). The power was interrupted while printing.
q q q q q
To clear feed jams in the Input areas
If most of the jammed sheet of paper is visible from the paper input bin or single-sheet input slot, carefully pull the jammed paper straight up and out using both hands. Realign the paper, and reload it.
Note Be sure to center paper with the paper guides. Also, verify that the paper guides are currently adjusted without bending the media. The printer will automatically resume printing.
42 Chapter 4 - Troubleshooting
To clear a jam from the interior area
2 If the jam is not visible in the input paper tray, open the printer door. Remove the toner cartridge. Be sure to protect it from bright light while it is outside your printer.
CAUTION Avoid touching the long, black, sponge roller inside your printer. Touching it may reduce output quality. Push the green paper release lever toward the back. If the paper jam is in the toner cartridge area but has not reached the fuser and roller area, reach inside and carefully pull the sheet straight forward and out. Do not pull the sheet straight up. This can damage your printer.
CAUTION Only use your hands to remove jammed paper. Using other objects can damage internal parts. If the paper jam is between the rollers, grasp the sheet with both hands and slowly pull it straight up and out.
Clearing paper jams 43
After removing all sheets and fragments of paper, replace the toner cartridge and close the printer door.
Your printer will automatically resume printing.

Indicator Lights (Continued) (2 of 2) It means this:
Printer is in Manual Feed mode.
Data Light is blinking
Make sure that the correct paper is loaded. Then, press and release the Control Panel Button to print.
Error Light remains on
Printer is out of paper. Printers EP door is open. Printer has a paper jam. Toner Cartridge is either missing or not installed correctly.
Add paper. Close the door. Clear the jam and resume printing. Install a cartridge, being careful to position it correctly. NOTE: The HP LaserJet 6L Pro has no mechanism for detecting the presence of a Toner Cartridge. If the Toner Cartridge is missing, the Error Light will remain off. Printing without a Toner Cartridge installed may cause a paper jam. If the Error Light remains lit after checking for these problems, and theres no paper jam, disconnect the power for 10 seconds, then reconnect to the power source. If, after taking these actions, the light remains on, refer to Chapter 7, Troubleshooting.
Error Light is blinking
The page may have too much data or may be too complex for the printers memory capacity.
Press and release the Control Panel Button to continue printing. There may be some data loss on the page. Hint: To avoid this in the future: 1. See your printer driver help for more suggestions regarding printer memory usage. 2. Reduce resolution to 300 dpi with your software. 3. Install additional printer memory. (See Chapter 6 for information on installing additional memory.)
All lights remain Printer is indicating either on an internal problem or a fatal error.
1. If you have added an additional memory card, try removing it. 2. Disconnect the power for 10 seconds, then reconnect it. 3. If all of the lights come on steadily again, try disconnecting the power for 15 minutes. If this error remains after completing the tasks above, see Chapter 7, Troubleshooting.
All lights are blinking
Printer is initializing or resetting (6L Pro) Memory card may be slower than 70 nsec (5L/6L)
No action is necessary. See Chapter 7, Troubleshooting.
Using the Control Panel 39
Service.book Page 44 Thursday, September 14, 2000 11:15 AM
Continuous self test
Note The HP LaserJet 6L Pro does not support the continuous self test. A continuous self test can be useful for troubleshooting paper path and other problems. To print a continuous self test: 3 Disconnect the printer from the power source. Press and hold down the Control Panel Button while connecting power. Continue holding the button for about five seconds. All lights will illuminate at once, then each will light in sequence. Release the button. The printer conducts its internal diagnostics routine, then prints the self-test page continuously until stopped. To stop the continuous self test (and reset the printer), press and hold the Control Panel Button for a few seconds until all lights begin lighting in sequence once again.
The self test does not print at the printers rated speed of 4 ppm (HP LaserJet 5L) or 6 ppm (HP LaserJet 6L). The engine test prints at the printers rated speed.
Printing an engine test
The engine test print can be used to verify that the print engine is functioning correctly. The Formatter PCA is completely bypassed during an engine test. Consequently, this test is useful for isolating engine printer problems. For the HP LaserJet 5L and 6L printers, the engine test prints a full page of vertical lines down the entire printable area. For the HP LaserJet 6L Pro, the engine test prints a full page of horizontal lines across the entire printable area. These engine test pages are useful for checking and adjusting registration. Note Perform the engine test with the printer covers in place, as shown in Figure 3-6. Refer to Engine Test in Chapter 7 for the engine test procedure.

Print engine control system
Laser and scanner drive
Based on information received from the Formatter, the DC Controller sends signals to the Laser/ Scanner Assembly to modulate the laser diode ON and OFF and to drive the Laser/Scanner motor. Refer to Image formation system later in this chapter for more information.
Paper motion monitoring and control
The DC Controller PCA controls paper motion by continuously monitoring the various paper sensors and coordinating the timing with the other print processes. For a detailed explanation of paper movement, and the interaction of photosensors and solenoid with the paper movement process, refer to Paper feed system later in this chapter.
12 V shutoff switch
The 12 volt DC power shutoff switch, Switch 101, located on the top of the printer, is activated by the printer door. The front door must be closed before the printer can resume printing.
Engine test switch
The Test Print, Switch 201, located on the DC Controller, is activated manually through an access hole at the front of the printer. This switch causes the print engine to perform a self-test diagnostic which bypasses the Formatter PCA and prints a full page of black vertical lines. This test is useful for troubleshooting printer problems because it isolates the print engine from the Formatter PCA. (See Chapter 7, Troubleshooting, to learn more about how to perform an engine test.)
The Motor is controlled by the DC Controller PCA. The Motor provides all of the printers paper movement.
Power system (on DC Controller PCA)
The AC, DC, and high voltage power supply circuits are all contained within the DC Controller PCA.
Step 2: Drum conditioning
After the drum is physically cleaned, it must be conditioned. This process consists of applying a uniform negative charge on the surface of the drum with the primary charging roller, located in the toner cartridge. The primary charging roller is coated with conductive rubber. An AC bias is applied to the roller to erase any residual charges from any previous image. In addition, a negative DC bias is applied by the charging roller to create a uniform negative potential on the drum surface. The amount of DC voltage is modified by the print density setting.
Step 3: Image writing
During the writing process, a modulated laser diode projects the beam onto a rotating scanning mirror. As the mirror rotates, the beam reflects off the mirror, first through a set of focusing lenses, off a mirror, and finally through a slot in the top of the toner cartridge, and onto the photosensitive drum. The beam sweeps the drum from left to right, discharging the negative potential wherever the beam strikes the surface. This creates a latent electrostatic image, which later is developed into a visible image. Because the beam is sweeping the entire length of the drum and the drum is rotating, the entire surface area of the drum can be covered. At the end of each sweep, the beam strikes the beam detect lens, generating the Beam Detect Signal (BD). The BD signal is sent to the DC Controller, where it is converted to an electrical signal used to synchronize the output of the next scan line of data.
Step 4: Image developing
At this stage of the process, the latent electrostatic image is present on the drum. The toner particles obtain a negative surface charge by rubbing against the developing cylinder, which is connected to a negative DC supply. The negatively charged toner is attracted to the discharged (exposed, grounded) areas of the drum, and repelled from the negatively charged (non-exposed) areas.
Step 5: Image transferring
During the transferring process, the toner image on the drum surface is transferred to the paper. A positive charge applied to the back of the paper by the transfer roller causes the negatively charged toner on the drum surface to be attracted to the paper. After separation, the drum is cleaned and conditioned for the next image.

General troubleshooting flowchart
When the AC power is first applied to the printer:
Both the printer motor and the laser/scanner motor rotate for six seconds. All of the LEDs illuminate for one second; the Ready LED will illuminate after three seconds.
AC Power is applied to the printer
If no error message is displayed, the Printer Door is firmly closed, and the toner cartridge is installed, but the motor does NOT rotate when AC power is applied to the printer: Verify that AC power is present at the input power receptacle and that the power cord is firmly inserted into the printer. Verify that FU102 is not open. (See Figure 7-2.) Verify that motor connector J1 is seated into J401 of the DC Controller. (See Figure 7-2.) Verify that the motor is correctly mounted to the printer chassis. If all of these conditions are correct, replace the DC Controller PCA and/or the motor.
Does the Printer Motor rotate in about 6 seconds?
Is the Control Panel functional?
No If the Control Panel is not functional: 3 Verify that the Control Panel connector J9 is seated into both the Control Panel and the Formatter PCA at J3. (See Figure 7-2.) Verify that the Formatter PCA is firmly seated into the DC Controller PCA. Perform an Print Engine Test. (See Figure 7-4.) If the engine test is successful, replace the Control Panel first, then, if necessary, the Formatter PCA. If the engine test is not successful, replace the DC Controller PCA.
Is an Error displayed?
If the control panel displays an error, refer to the appropriate section in this chapter to correct the error.

High-voltage power supply check
The High-Voltage Power Supply PCA provides the necessary voltages for the electrophotographic processes. A method for verifying the high-voltage system is given in the table below.
Table 7-4 Check
High-voltage power supply check Action
Visually inspect the three connection points on the underside, right end of the toner cartridge. If they are dirty or corroded, clean the connections. Use alcohol only. If damaged, replace the toner cartridge. (See Figure 7-5 below.) This assembly uses spring-loaded pins to contact the toner cartridge. (See Figure 7-6 on the following page.) Verify that the pins are not dirty or corroded and that the spring-loading action is functional. If the pins are dirty, clean using alcohol only; if damaged, replace the High Voltage Connector Assembly.

Paper curl is inherent to the laser printing processes, and occurs when paper is subjected to heat. Paper curl tends to relax as the paper cools while resting on a flat surface. The specification for maximum paper curl when the paper is lying flat before print is 5 mm (0.2 inches). Although paper curl cannot be totally eliminated, some steps can be taken to lessen its impact, as suggested in the following table.
Paper curl troubleshooting Recommended action
Try using the front output slot to shorten and straighten the paper path. The recommended printing surface of the page is usually marked on the end of a ream of paper by a small arrow and the phrase print this side first. If the incorrect side was face up, turn the paper over. Load paper into the Paper Input Tray with the recommended printing surface facing the front of the printer. Over time, paper assumes the characteristics of its storage environment. (In a humid environment, paper absorbs moisture. In a dry environment, paper loses moisture.) Paper with higher moisture contents will tend to curl more. Evaluate the storage conditions of the paper. All paper is manufactured differently (texture, moisture content, drying processes, composition, etc.). Change the type of paper being used and reevaluate the paper if curl results.

The HP LaserJet 6L Pro is small and cheap LaserJet that looks like an inkjet. Its unusual shape was first adopted in the 5L. The HP LaserJet printer is ideal for business users in Microsoft Windows, DOS or OS/2 environments who want the convenience and confidentiality of a desktop laser printer. This true 600 dpi Laser with 6 ppm engine carries the same instant-on low-power fuser, and the same single multi-purpose button - there is no power switch. Paper feeds and ejects vertically. The mechanicals get top marks though, and the front section swings out clean; clearing a paper jam is easy. You can also choose to front-eject the paper, though there is no collection tray there. And you can feed envelopes through a straight paper path. The software does a pre-installed check of your hardware specs, such as processor and memory. There is a possibility to use both drivers that can boost your productivity.
