60 Phaser 740 and 750 Color Printers
Single light, horizontal line in all the prints
This is probably caused by a defective
photoconductive belt onto which toner
will not transfer.
1. Replace the imaging unit.
2. Replace the second bias transfer
roller. Inspect it for loose roller
contacts. Grease the end of the
roller shaft with conductive grease.
Large, random light smudges
Spots such as those illustrated are
caused by fingerprints on the
photoconductive or accumulator belt.
Often, the smudges will gradually fade
with additional printing. Alternately,
the imaging unit will have to be
replaced.
Fingerprints can be removed by
applying some toner (any color) to the
fingerprints and rubbing lightly with a
cotton-tipped swab. Don’t remove the
toner. The printer will remove the toner
with its cleaning blade. Remember not to
expose the imaging unit to ambient light for
more than a minute.
