Phaser 2135 Color Printer
Unexpected colors
The colors produced by the printer are dramatically different from the color you
expected.
1.
Look for dirt or contamination
on the LED heads. Clean them
with a clean, alcohol-soaked,
lint-free wipe.
2.
If it appears that a single
primary color is missing, check
that imaging drum’s toner
cartridge to see if it is empty;
the toner sensor board may not
be detecting the empty sensor.
3.
Inspect and clean the imaging
drum unit’s power terminals
Ensure the spring-loaded pins
travel smoothly up and down.
4.
Replace any imaging drum
units you suspect are defective.
5.
Are the LED heads wiring
harnesses undamaged and
properly seated?
6.
Is +3.8V (red wire) supplied to
Pin 3 of each LED head
assembly? If yes, replace the
LED head assembly.
7.
Is +3.8 V supplied to the POWER connector pins 1, 2, 3, 4, 5, 6, 7 and 8 on
the junction board or at the 16-pin interconnect near the top cover hinge
(under the top shield plate). Inspect the junction board’s wiring connectors.
If the voltage is not OK, replace the low-voltage power supply.
8.
If +32 volts supplied to the POWER connector pins 7, 8, 9 and 10 on the
engine controller board? Inspect the wiring harnesses or replace the
low-voltage power supply.
9.
Is +32V supplied to the HVOLT connector Pin 5 of the engine board. If not
replace the engine controller board. Transfer the old engine controller
board’s EEPROM (lower-right corner of board) to the new engine controller
board.
10.
Inspect the high-voltage wiring harnesses.
11.
Replace the high voltage power supply.
