Table 7-38 Blank page
Possible cause Recommended action(s)
The software configuration is incorrect
(intermittent problem).
Make sure that the software program is
not sending incorrect page-length
requests or extra page-eject commands.
The network configuration is incorrect.
Some sharing devices on networks
might generate a blank page as a print-
job separator.
Check with the network administrator.
Multiple feeds are occurring. The
printer might be feeding two or more
pages at on time (intermittent problem).
Remove the media from the tray and
flex the stack in one direction and then
the other to separate the pages. Do not
fan the stack. Replace the stack in the
tray.
The sealing tape was left in the print
cartridge.
Remove the sealing tape.
The print cartridge is empty or defective. Replace the print cartridge.
The laser/scanner shutter door is not
opening correctly.
1 Remove and reseat the print
cartridge.
2 Verify that the laser/scanner
shutter door can open correctly. If
necessary, replace the laser/
scanner assembly. See
Laser/
scanner assembly.
No transfer-roller voltage is being
generated.
Without transfer-roller voltage, toner
does not transfer correctly from the
surface of the drum to the paper.
Perform the half self-test functional
check (see
Half self-test functional
check) to check the
electrophotographic process. If
necessary, replace the transfer roller.
See
Transfer roller .

The high-voltage connector springs are
dirty or damaged.
The high-voltage connector springs
protrude into the print cartridge cavity.
Clean the springs if they are dirty.
Replace the springs if they are
damaged or missing.
No drum ground path exists. When no drum ground path exists, the
drum cannot discharge. The negative
charge on the drum repels toner, and
leaves a nearly-white page (possibly
with bubbled print). Check the drum
ground that runs from the contact point
in the center of the print drum.
The high-voltage circuit is defective. Replace the power-supply assembly.
See
Power supply.
The laser/scanner cable is defective. Low-level signals that are exchanged
between the laser/scanner assembly
and the dc controller PCA might be
affecting the laser output. Replace the
laser/scanner cables.
