thanks for help

In a lot of respects, this is a good printer: quite quick, very clear printing, takes 160 gsm card, works without Windows. I started having problems with this printer around the end of the first year, after just normal use.

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.

Printing

Selecting media sizes
The type of media you select will affect printer performance and print quality. The paper input bin can hold up to 100 sheets of 75 g/m2 (20-lb bond) paper. The single-sheet input slot is designed to hold one sheet. Both can be adjusted to hold media measuring from 76.2 by 127 mm (3 by 5 in) to 215.9 by 355.6 mm (8.5 by 14 in). This includes the following paper and envelope sizes:

q q q q q q q q q q

A4 (210 by 297 mm, 8.27 by 11.7 in) Letter (215.9 by 279.4mm, 8.5 by 11 in) C5 Envelopes (162 by 229 mm, 6.38 by 9 in) Other Custom-Sized Media Legal (215.9 by 355.6 mm, 8.5 by 14 in) COM10 Envelopes (104.7 by 241.3 mm, 4.125 by 9.5 in) B5 Envelopes (176 by 250 mm, 6.93 by 9.85 in) Executive (184.15 by 266.7 mm, 7.25 by 10.5 in) DL Envelopes (110 by 220 mm, 4.33 by 8.67 in) Monarch Envelopes (98.4 by 190.5 mm, 3.875 by 7.5 in)

Selecting media sizes 27

Insert all media lengthwise (portrait) into the printer. If you want to print horizontally (landscape), make this selection through your software. Do not print on paper smaller than 76.2 by 127 mm (3 by 5 in).

28 Chapter 3 - Printing

Selecting the output paper path
1 CAUTION To avoid paper jams, do not switch the paper path lever once printer begins to feed paper. 1 Set the paper path lever to the upper position to use the paper output bin. By doing so, the sheets will stack in the correct order. Set the paper path lever to the lower position to use the heavy media output slot. This straight-through path is the best output option to print postcards, transparencies, labels, envelopes, and heavy paper (100- to 157-g/m2 [28- to 42-lb] bond weight).
CAUTION If using the straight-through paper path, do not allow more than one transparency, 20 sheets of paper, or other media to stack up in front of the heavy media output slot. A paper jam could result.

Adding paper

When adding paper to an existing stack in the paper input bin, always remove and realign all paper before reloading to avoid multiple paper feeds or jams.
Selecting the output paper path 29
Using the single-sheet input slot
1 You can print one sheet of paper at a time without unloading the paper input bin. To do so, load one sheet into the single-sheet input slot. The printer will take from the single-sheet input slot before it takes from the input bin. Note The single-sheet input slot is helpful to use when the first page of your job is different from the rest. For example, you may want the first page of your print job on letterhead, or you may want to print an envelope first. 1 Center the paper guides to the approximate size of the sheet you want to use. Insert one sheet of paper into the single-sheet input slot. Readjust the paper guides to center the sheet.

30 Chapter 3 - Printing

Printing on letterhead and envelopes

Letterhead

1 If you print one sheet of letterhead followed by regular sheets of paper, place a sheet of letterhead into the (A) single-sheet input slot and regular sheets of paper into the (B) paper input bin. If you print several sheets of letterhead in succession, fill the paper input bin (B) with the letterhead. Insert the letterhead with the print side forward and the top side down.
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

Envelopes

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

Printing tasks
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.

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.
Use only labels specified for HP LaserJet printers.
Printing on special media 37

Managing toner cartridge

It is recommended that you use HP LaserJet toner cartridge. HP has designed the printer, toner cartridge, and toner formula to work together to give you optimal image quality from your printer. To order an HP LaserJet toner cartridge, see appendix A. You can expect a toner cartridge to print approximately 2,500 pages when you are printing typical business letters with text covering about 5% of the page. A page containing graphics uses more toner and shortens the life of the cartridge.
Extending toner life through EconoMode
An excellent way to extend the life of your toner cartridge is by using EconoMode. EconoMode uses approximately 50% less toner than normal printing. The printed image is much lighter, but is adequate for printing drafts or proofs. You can set the EconoMode option through your software (see to Help for more information). Note When printing a best-quality document, you must deselect the EconoMode check box.

38 Chapter 3 - Printing

Extending toner life by redistributing toner
Areas of faded print are often an indicator that the toner cartridge is near the end of its toner life. You can temporarily reestablish print quality by redistributing the remaining toner in the cartridge. (This is typically successful only one time.) To redistribute toner Open the printer door and remove the toner cartridge. Hold the toner cartridge by the handle and pull it toward you so that it slides out of the plastic grooves. (Remember to protect the cartridge from light.) Briskly roll the toner cartridge back and forth to redistribute the toner evenly inside the cartridge. Reinsert the toner cartridge and close the door.

The printer will automatically resume printing. 4

Paper will not feed 45

Cleaning your printer
1 To prevent excessive wear and preserve print quality, keep the printer free of excessive dust and debris. Note If there are excessive amounts of toner inside your printer, your toner cartridge may be defective. It is recommended that you use HP LaserJet toner cartridges to ensure high quality printing and to reduce incidents of excessive toner in your printer.
WARNING! Before cleaning your printer, disconnect it from the power source.
CAUTION Using ammonia-based cleaners on or around the printer can cause damage to the printer. Also, do not touch the black sponge roller inside the printer. doing so can reduce the print quality. 1 Clean the outside of the printer with a slightly damp, lint-free cloth (use only water). Clean the inside of the printer with a dry, lint-free cloth. Remove all dust, spilled toner, and particles of paper.
Note If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into the fabric.

Envelope storage

Proper storage of envelopes helps contribute to good print quality. Envelopes should be stored flat. If air is trapped in an envelope, creating an air bubble, the envelope may wrinkle during printing.
Card stock and heavy media
Many types of card stock can be printed from the paper input tray, including index cards and postcards. Some card stock performs better than others because its construction is better suited for feeding through a laser printer. For optimum printer performance, do not use paper heavier than 163g/m2 (43 lb). Paper that is too heavy might cause misfeeds, stacking problems, paper jams, poor toner fusing, poor print quality, or excessive mechanical wear. Note Printing on heavier paper may be possible if the tray is not filled to capacity, and paper with a smoothness rating of 100-180 Sheffield is used.
Guidelines for using paper 79

Card stock construction

Smoothness: 135-163 g/m2 (36-43 lb) card stock should have a smoothness rating of 100-180 Sheffield. 60-135 g/m2 (16-36 lb) card stock should have a smoothness rating of 100-250 Sheffield. Construction: Card stock should lie flat with less than 5 mm (0.2 in) of curl. Condition: Make sure card stock is not wrinkled, nicked, or otherwise damaged. Sizes: Use only card stock within the following size ranges: Minimum: 76 by 127 mm (3 by 5 in) Maximum: 216 by 356 mm (8.5 by 14 in).

Card stock guidelines

If cards curl or jam, print using the heavy media output slot. Set margins at least 2 mm (0.08 inch) away from the edges of the paper.

Paper feed system

Both the Paper Input Tray and the Single Sheet Input Slot merge into one, main input area. Paper placed in either of these areas enables the Paper Out Sensor (sensor 202), which informs the DC Controller that paper is present. When the printer receives a print job and is ready to print, the DC Controller enables the Laser/ Scanner Assembly and the Motor. Paper motion begins when the DC Controller energizes solenoid SL1. This causes the paper pick up roller to rotate once. Two actions occur as a result of this rotation. First, the paper kick plate pushes the paper against the pick-up roller. Second, the pick-up roller grabs the top sheet and advances it to the Feed Assembly drive rollers. To ensure that only one sheet is fed, a main separation pad, along with two subpads, hold the remainder of the stack in place. The feed assembly drive rollers advance the paper to the Paper Registration photosensor (PS203). This sensor informs the DC Controller of the exact location of the papers leading edge, so that the image being written on the photosensitive drum can be precisely positioned on the page. The feed assembly drive rollers then advance the paper to the transfer area where the toner image on the photosensitive drum is transferred to paper. After the image is transferred, the paper enters the fusing assembly where heat from the fuser and pressure from the Pressure Roller permanently bond the toner image to paper. The Paper Exit Sensor (PS201) determines that paper has successfully moved out of the fusing area. The fusing assembly exit rollers deliver paper to either the Output Paper Bin or the Front Output slot, depending upon the position of the Face-up/Face-down lever. Figure 5-5 shows a simplified paper path and the locations of the photosensors and rollers.

Basic sequence of operation
The Formatter PCA and the DC Controller PCA share information during printer operation. The DC Controller-to-Formatter Connector (J201) forms a link that operates as a serial data bus. This allows printer status, command information, and dot-image data to be passed between the two PCAs. Figure 5-7 shows the general timing of the printer events. The following events take place during normal printer operation:
