Figure 5-12. Cleaning the transfer charger wire

Transfer

Developer roller

Return the cleaning blade to its receptacle.

Replace the drum cartridge, then close the case.

Test the print quality by turning the printer off, then turning the

power on while holding down the

ERROR CLEAR

button. The

status indicator will display seemingly random values as the

printer’s

memory

is checked; when the warm up indication (- - )

appears, release the

ERROR CLEAR

button.

When the printer is warmed up, the status indicator displays

0~.

Pressing the

ERROR CLEAR

button switches back and forth

between

OC,

which prints a vertical line pattern, and 1 C, which

prints the

GQ-3500’s

text characters. To make

test print, press

the

PAPER FEED

button. (If you hold down the

PAPER FEED

button for more than two seconds, the printer continues to produce

test prints until you press the

SHIFT

button.)

Examine the test print,

checking

to see that the image is clear and

distinct. If it is, place the GQ-3500 in its normal printing mode by

pressing the

ON LINE

button. If the test print is blurred or defective

in other ways, replace the drum cartridge as described in

the

User

Maintenance section of this chapter. If the quality is still poor,

contact a qualified service representative.
