Cleaning the Printer and Accessories Preventative Maintenance

Overview 4-1

Cleaning the Printer and Accessories
To maintain high print quality and performance, thoroughly clean the printer and the paper handling accessories:
Every time you change the Toner Cartridge (run a cleaning page). After printing approximately 15,000 pages. Whenever print quality problems occur.
Clean the outside surfaces with a lightly water-dampened cloth. Clean the inside parts as indicated in Table 4-1. Observe the warning and caution below. WARNING! Before you begin these steps, turn the printer off and unplug all power cords to avoid shock hazard. Be careful when cleaning around the Fusing Assembly area. It may be hot. CAUTION To avoid permanent damage to the Toner Cartridge, do not use ammonia-based cleaners on or around the printer. Do not touch the transfer roller. Skin oils on the roller can reduce print quality. If toner gets on your clothes, wipe it off with a dry cloth and wash your clothes in cold water. Hot water sets toner into fabric.

PML is a Printer Management Language that allows remote configuration and status readback through the I/O Ports.

Control Panel

The Formatter PCA sends and receives printer status and command data via a Control Panel PCA. See Using the Control Panel on page 3-2, and Alphabetical Printer Messages on page 7-16 for more information.

Formatter System 5-17

Image Formation System
The image formation system is the main part of the printer, and consists of six stages:
1. Cleaning 2. Conditioning 3. Writing 4. Developing 5. Transferring 6. Fusing
When the Formatter Board sends the print signal to the DC Controller Board, it drives the main motor to rotate the photosensitive drum, the developing cylinder, the primary charging roller, and the transfer charging roller. The primary charging roller places a uniform negative charge on the surface of the photosensitive drum. The laser beam modulated by the video signal is illuminated on the photosensitive drum surface to form the latent image on the drum with the laser diode. The latent image formed on the photosensitive drum is changed to a visual image by the toner on the developing cylinder, then transferred to the paper by the transfer charging roller. The residual toner on the photosensitive drum surface is scraped down with the cleaning blade. The potential on the drum is uniformed by the primary charging roller to prepare for a new latent image. The cartridge has a toner sensor that detects the remaining toner level and the presence of the cartridge. If the toner in the cartridge becomes lower than the specified level or if there is no cartridge in the printer, it is reported to the Formatter.
5-18 Functional Information

Figure 5-6

Image Formation System After the image has been transferred to the paper, it is then fused onto the paper by heat and pressure at the Fuser.
Image Formation System 5-19

Toner Cartridge

A major portion of the Image Formation system is contained in the cartridge as shown in the figure below. The Toner Cartridge is the heart of the Image Formation System. It houses the cleaning, conditioning, and developing steps of the process. The Toner Cartridge contains the photosensitive drum, primary charging roller, developing station, toner cavity, and cleaning station. Including these components that wear, degrade, or are consumed in the replaceable Toner Cartridge eliminates the need for a service call when replacement is required. The printer also has a new cartridge drive system that minimizes banding, with more constant paper speed.

Figure 5-7

5-20 Functional Information

Photosensitive Drum

The special properties of the photosensitive drum allow an image to be formed on the drum surface and then transferred to paper. The drum is an aluminum cylinder. The outside of the cylinder is coated with a layer of organic-photoconductive material (OPC) which is nontoxic. The OPC material has properties similar to a photo-resistor. It becomes electrically conductive when exposed to light. (The negative charges deposited on the drum are conducted to the ground potential of the drum base.) Areas not exposed to light remain non-conductive and maintain their negative charge. The aluminum base of the photosensitive drum is electrically connected to ground potential.

10 If the Control Panel displays READY, OFFLINE, or POWERSAVE ON, go to the next section. If it indicates any other message, repeat this section from step 1.

Print the Event Log

The printers internal Event Log stores the last 30 errors and can be printed at any time. To print the Event Log:
Press [Menu] until INFORMATION MENU appears. Press [Item] until PRINT EVENT LOG appears Press [Select] to print the Event Log.

Interpret the Event Log

The Event Log is the key tool in troubleshooting printer problems. Figure 7-2 shows a typical Event Log. The Event Log shows the current page count at the top left of the page with the printers serial number directly to the right of the page count. The left column is the error sequence number, with the error listed at the top (the highest sequence number is the most recent error logged). The next column is the page count at the time of the error, and the last column is the Personality (PCL or PostScript) column or the cause of the jam at the time of the error.

7-14 Troubleshooting

The Event Log may record errors in a different format than the Control Panel Display. For example, should a 50.1 FUSER ERROR / CYCLE POWER be displayed on the Control Panel, the Event Log will record a 50.02.01 error, with the 02 signifying that 2 sensors were blocked. Likewise, when a 13.1 through 13.9 are displayed on the Control Panel, the Event Log will record a 13.0x.01 through 13.0x.09, where x= the number of sensors blocked in the printer. Hint Whenever a 13.xx appears on the Control Panel, a good practice is to clear all the jammed paper from the printer and print the Event log. If you cannot print the Event Log, you can still display it on the Control Panel. Write the error next to the last error logged. The last error is the error at the top of the Event Log printout with the highest number in the left-most column. To interpret the Event Log:
Each individual entry in the log is called an error, and all errors occurring at the same page count are called an event. Read the Recommended Action for each error comprising an event to gain a clear picture of what took place during that event. Events usually conclude with a time-out, or no response from device (Error 66.xx in the Event Log) which requires a power cycle of the print engine. Use the Event Log table in this section to associate errors in the Event Log with the Control Panel error message. Follow the Recommended Action listed in the table for each error or event.

Paper path contamination or damage.

The purpose of the Half Self Test Check is to determine which process is malfunctioning. Perform the test as follows: Print a Configuration Page from the Control Panel INFORMATION MENU. Open the top cover after the paper advances half-way through the printer (about five seconds after the Main Motor begins rotation). The leading edge of the paper should have advanced past the Toner Cartridge. Remove the Toner Cartridge. Open the Toner Cartridges drum shield to view the drums surface.
If a dark and distinct toner image is present on the drums surface, assume that the first four functions of the electrophotographic process are functioning (cleaning, conditioning, writing, and developing - see Chapter 5), and troubleshoot the failure as a transfer or fusing problem. If no image is present on the photosensitive drum, perform all the following functional checks:

7-74 Troubleshooting

Drum Rotation Functional Check
The photosensitive drum, located in the Toner Cartridge, must rotate for the print process to work. The photosensitive drum receives its drive from the Main Drive assembly. To verify whether the drum is rotating: 5 Open the top cover. Remove the Toner Cartridge. Mark the cartridges drive gear with a felt-tipped marker. Note the position of the mark. Install the Toner Cartridge and close the top cover. The start-up sequence should rotate the drum enough to move the mark. Open the printer and inspect the gear that was marked in step 3. Verify that the mark moved. If the mark did not move, inspect the Main Drive assembly to ensure that it is meshing with the Toner Cartridge gears. If the drive gears function, and the drum does not move, replace the Toner Cartridge.
This test is especially important if refilled Toner Cartridges are in use.
