ENTERING DIAGNOSTICS:

Turn power on and within 4 seconds press the following sequence:

‘Clear’, ‘Auto’, ‘Clear’,’Auto’

(The ‘Auto’ button is also sometimes referred to as

the “Exposure Mode” button)… The entire display including the numerics will go totally

blank. Use the quanitity select keys (1’s & 10’s) to select the code you wish to enter.

• CHECKING TOTAL COPY COUNT: (22-5)

Enter diagnostics, select ‘22’, ‘Print’ followed by ‘5’, ‘Print’...The copy count will flash

2 digits at a time for a total of six digits (for example: 01 23 45 would indicate 12,345

copies). (Or you can do it the easy way like the customer would by holding the ‘Clear’

button for 7 seconds).

Use ‘22’, ‘Print, ‘12’, ‘Print’ to get the current drum count.

• DRUM SYMBOL: See page 132 for details on how the drum count

resets with a new cartridge & also how to reset the count from diagnostics.

STATUS CODES:

• A1/A2 CODES: SDF Document Jams

• CH CODE: Toner Cartridge not present or not seated properly.

• H2 CODE: Thermistor open

• H3 & H4 CODES: H4=Low Fuser Temperature, H3=High Fuser

Temperature… could be bad Heat Lamp, bad Thermal Fuse, bad Thermistor…

or toner build up on the thermistor caused the Thermal Fuse to blow.

Sometimes electrical storms can also cause false H4 codes.

Often, the Heat Lamp and Thermal Fuse check out ok … in the case of an H3

this is because the Thermal Fuse is a self resetting device. You should check

out the Thermistor for positioning & cleanliness and of course, reset the code:

• RESETTING H CODES (14) Enter Diagnostics as shown above. Select

14, press ‘Start’, Then turn power off & back on

• L1/L3 CODES: Scanner problems

• L4 CODE: Main Motor problem

• L5 CODE: Lens drive problem

• P CODE: Paper feed problem

• U2 CODE: Means “memory failure”… To clear this code, enter

Diagnostics, select ‘16’ followed by ‘Print’… then exit diagnostics.

• U5 CODE: SDF High Temperature (or SDF Thermistor failure)

• WHAT DOES THE LIGHT TO THE LEFT OF THE SDF MEAN?

That’s the SDF Jam Light. Use code ‘2-2’from diagnostics to test any doc. Path

Sensor. Each sensor has it’s own light on the display which will go on / off

whenever the sensor is actuated.
