xxi Service Manual

1. General Information Maintenance Approach
The diagnostic information in this manual leads you to the correct field replaceable unit (FRU) or part. Use the error code charts, symptom index, and service checks to determine the symptom and repair the failure. After you complete the repair, perform tests as needed to verify the repair.

Tools
The removal and adjustment procedures described in this manual require the following tools and equipment:

· · · ·

Magnetic tip Phillips screwdrivers, large and small Flat-blade screwdriver Analog volt ohmmeter (a digital volt ohmmeter may also be used) Needle nose pliers

When you make voltage readings, always use frame ground unless another ground is specified.

Paper Feed Operation · ·
Paper can be fed into the printer from the Multi-Purpose Tray (150 sheets) or from the Second Cassette Tray (Tray 1, 250 sheets). The Optional Third Cassette Unit (Tray 2 option, 250 sheets) adds another feeding method. Its structure is the same as that of the Second Cassette Tray.)

1-2

Multi Purpose Tray When the paper take-up solenoid 1 (SL3) energizes, the transport motor (M2) drives the paper take-up roller via the paper take-up clutch. The paper take-up roller rotates one revolution. At the same time, the depressing cam rotates and releases the paper lift-up plate to feed the top sheet of paper. The paper is transported to the synchronizing roller section by the transport rollers. The transport rolls are mounted free on the shaft of the paper takeup roller and rotate independently of the paper take-up roller. The transport rolls rotate as the transport roller rotates. The fixed separating pad separates paper and prevents multiple paper feeds. The paper empty sensor 1 (PC5) detects paper in the multi-purpose tray.

General Information 1-3

Second Cassette (Tray 1) When paper take-up solenoid 2 (SL7) energizes it rotates the paper take-up roller which feeds the top sheet of paper. Paper empty sensor 2 (PC11) detects paper in the second cassette. Paper near empty sensor 1 (PC10) detects when the number of sheets of paper in the tray becomes less than 50. The combination of switches S1 and S2 on the 2nd paper size/cassette detecting board (PWB-E) detect the presence of the cassette and the size of paper in the cassette.

1-4

Third Cassette Unit (Tray 2 Option) The third cassette is constructed in the same way as the second cassette.

General Information 1-5

Drum Cartridge Toner Full Detection
The drum cartridge toner full board (PWB-D1), on top of the image transfer belt assembly, determines when the PC drum waste toner box is full. Waste toner full is detected by an LED (LED1) and a photo-sensor (PT1) on the PWB-D1. Light from the LED (LED1) passes through the LED passing window, is reflected by a mirror in the drum cartridge, and then received by the photo sensor (PT1). The amount of this light determines whether the drum cartridge is nearly full or full.

1-6

Synchronizing Rollers
The synchronizing rollers adjust any skewed paper transported from the paper take-up/feed section. The rollers match the leading edge of the image on the image transfer belt with the leading edge of the paper. The paper synchronizing sensor (PC1) detects when the leading edge of paper has reached the synchronizing rollers.

General Information 1-7

Paper Type Detection
The overhead projection (OHP) sheet detect board (PWB-D2), consisting of an LED (LED1) and a photo sensor (PT1), determines whether transparencies or plain paper is being fed through the machine.

When plain paper is feeding, the light from the LED reflects off the surface of the paper, and strikes PT1.

1-8

When a sheet of OHP transparencies is feeding, the light from the LED passes through and PT1 receives no light.

General Information 1-9

Development
Toner Empty / Toner Cartridge Detection
Toner Empty Detection Light from the toner empty detection LED (LED1) on the toner empty/toner cartridge detecting board (PWB-B) is reflected by a mirror in the toner cartridge and received by photo sensor (PT1). The amount of light received by the photo sensor determines whether the toner is empty or nearly empty.

1-10

Toner Cartridge Detection Light from the toner cartridge detection LED (LED2) on the toner empty/toner cartridge detecting board (PWB-B) is reflected by the toner cartridge surface to the photo sensor (PT1). The toner cartridge is detected during warm up.

AIDC Sensor and Erase Lamp
Automatic Image Density Control (AIDC) The AIDC sensor detects the image density of the AIDC mark formed by toner on the PC Drum to determine proper charging bias and developing bias. The sensor is located on the AIDC/erase lamp board (PWB-C) on top of the image transfer belt. AIDC detection is accomplished with one LED (LED1) and two photo sensors (PT1, PT2).

General Information 1-11

AIDC detection is done for each Color Toner Cartridge after the developing rack position initializes.

1-12

Erase Lamp Nineteen LEDs are placed in a row on the AIDC/Erase Lamp Board (PWB-C). Following developing, the surface of the PC Drum is exposed to light from these LEDs to neutralize negative the charge on the areas to which no toner has been attracted.

2. Diagnostic Information
The diagnostic information in this chapter leads you to the failing part. Before you replace an entire assembly, determine if just the defective part is available in the parts catalog. Some diagnostic procedures indicate the parts catalog location of the part to be checked by including the assembly number and reference number in parenthesis. Some part numbers are also included. Use the error code tables, symptom table, service checks and the diagnostic aids chapter to determine the symptom and repair the failure. After you complete the repair, perform the appropriate tests to verify the repair. If an error is displayed, locate it in the following Operator Error Message Table, or the Service Error Message Table and take the appropriate action. If an error message appears while you are working on the machine, go to the error message table and take the indicated action. Use the Locations chapter to find connector, board, and pin information. The sequence given in the service check is connector, board, and pin. The board uses only a letter for an identifier. For example, connector CN8A-3; CN8 = connector, A = board, -3 = the pin.

Start
Initial Check
Before you start troubleshooting, check the following: Installation Environment

· · · ·

The power supply line voltage is plus or minus 10% of the rated line voltage. The machine is securely installed on a level surface in a wellventilated place. The room temperature is between 10 and 32°C (50 and 90°F) and the relative humidity between 20 and 80%. Avoid sites generating ammonia gas, high temperature or high humidity (near water faucets, kettles, humidifiers), cold spaces, near open flames, and dusty areas.
