Random Marks
Random marks are nearly always due to a mechanical problem or
due to foreign matter loose in the printer or in the print cartridge.
Inspect and clean the inside of the printer carefully and correct any
problems found.
Skew, all edges
If the test print frame is parallel to all edges of the page but the
margins are not all the same width
If the test print frame is not parallel to the left and right edges of the
paper, the paper has skewed in the paper path. Check the paper
path for obstructions. Make sure the paper in the tray is loaded
properly and is undamaged. Check the prealigner, drive, and
auxiliary rollers, springs, and backup rollers for dirt, wear, or
damage; refer to the parts catalog for repair kits for broken bellcrank
spring attachment hooks on the sideframe. Make sure all the
bellcrank assemblies pivot freely. Check the gear train for damage or
binds.
Skew, top and bottom only
If the test print frame is parallel to the left and right edges of the
paper but not parallel to the top and bottom, the printhead skew
needs to be adjusted.
See
“Printhead Skew - Level 1” on page 59
and
“Printhead Skew - Level 2” on page 60
Stalled (diamonds on display)
Check the continuity of the cable from (10P/10R/12R/12C/12L) J7
(16L) J5 on the system board to the operator panel. Next, reseat the
ROM and memory SIMMs and POR. This condition can also occur
on models 10R/12R/12L/12C if a network card is installed without
the accompanying DC power card.
