Transfix roller pressure spring adjustment
1.
Print the service test print YMCKRGB in duplex mode. Duplex mode can be set using
the front panel menu
Printer Default Settings
.
2.
If any of the prints are wrinkled on both the left and right sides of the print, the
drum/transfix assembly must be replaced. No adjustment will solve the problem.
3.
If wrinkling is only present on the left or right side of any print, note which side.
4.
Remove the front cover to access the drum/transfix assembly.
5.
Draw a reference mark on the both the left and right spring set screws.
6.
On the side of the printer corresponding to the wrinkling, tighten the set screw
clockwise 1/8 of a revolution, using a 4 mm hex driver. On the side that does not
wrinkle, loosen its set screw 1/8 of a revolution.
Note
Whatever adjustment is added to one side must be taken away
from the other side to maintain roller balance.
7.
Reassemble the printer and again print the service test print YMCKRGB in duplex
mode.
8.
If wrinkling still occurs on the same side, repeat Steps 6 and 7.
Do not adjust the set screws more than 3/8 of a revolution from their original position.
Any adjustment beyond this point results in ink adhesion problems.
9.
If wrinkling continues to occur, replace the drum/transfix assembly.
