Sheet Feeder

An optional 500-sheet feeder is available. As with the LaserWriter 16 600 PS design, the sheet feeder fits squarely beneath the printer or the duplexer, if present to form a dual front-loading cassette arrangement. An envelope cassette is available for the sheet feeder only. The feeder has a receptacle connector that mates with the printer and has its own circuit board. However, the feeder does not have its own motor. Instead it derives mechanical drive directly from the gear train above,...

Multipurpose Tray Paper Jams

There have been a number of reported problems with the multipurpose tray and its associated components. In the process of resolving these problems, service providers may inadvertently dislocate the solenoid flapper or actuator that is responsible for releasing the multipurpose tray paper pickup roller so that it can complete its paper pickup cycle. When this occurs the paper pickup roller rotates constantly resulting in paper jams if paper is present and annoying noises whenever the printer is...

When the AutoSelect feature built into PostScript searches for letter size paper, the cassette will be passed over and the controller assumes that the paper should be in the...

Print Process Description Charging

During this stage, the drum surface receives a uniform negative charge. Note The drum surface is made of a photoconductive material and the inner part of the drum is made of a conductive material. This negative charge is actually placed onto the outside surface of the photoconductor layer. The charge is imparted by the bias charge roller BCR within the toner cartridge. The BCR is a conductive roller in contact with the drum surface and is supplied with a discharge voltage by the high-voltage...

Manual Feed Clutch Gear

Before you begin, remove the following Manual feed pickup roller holder 1 Release the latch and slide the cam off the shaft. 2 Press the lever gear and pull the manual feed clutch gear from the multipurpose frame assembly. Note Do not separate the two gears on the Manual Feed Clutch Gear 922-1964 . Separating the gears may cause the small spring inside the gear to fall off, causing the pickup roller not to rotate, resulting in a timeout paper jam. You cannot see this spring unless you separate...

Image Quality Problems

It can be easily determined whether an image quality problem is being caused by the print engine or by the I O controller board by producing a service test page. The service test page can be generated by jumpering the two pins of connector J101 on the I O controller board. If the test page is normal, but the regular prints have an image quality problem, the problem is probably with the I O controller board. If the test print has also the image quality problem, the problem is probably in the...
