Poor fusing after PowerSave
After spending several hours in PowerSave
mode, the printer may produce output with
toner improperly fused to the page. Output may
not improve until 20 to 50 pages have been
printed or the printer undergoes a power cycle.
This issue is most commonly seen when the
printer is first used in the morning, after
spending the night in PowerSave mode.
5 Check connectors J3036 on the registration
motor and J117 on the DC controller PCA.
6 Replace the registration motor if the motor
fails the component test.
7 Replace the DC controller PCA.
Background information
The high voltage contacts for the secondary
transfer roller are located on the secondary
transfer assembly. Using the cams on the
bottom of the secondary transfer assembly,
these contacts move into place against the
secondary transfer roller every time a page is
printed. The cams are engaged by firing a
solenoid which engages the clutch mechanism
on the secondary transfer assembly.
The following conditions must be met in order
for this issue to occur:
•
The PowerSave setting must be High (this is
the default setting for 220 volt printers).
•
The ambient room temperature must be less
than or equal to 60º F (15º C).
•
The printer must spend six to eight hours in
PowerSave mode (shorter or longer periods
of time will not cause this issue).
The timing for moving the high voltage contacts
into place varies because, depending on the
media source selected, media moves at a
different speed prior to registration. Tray 1
feeds at .5 speed, trays 2 and 3 feed at 1.5
speed, and tray 4 feeds at full speed. If the
solenoid or clutch cannot move the secondary
transfer roller high voltage contacts into place
once the media has reached the registration
assembly, a 59.E0 error posts on the control
panel.
To workaround this issue, change the
PowerSave setting to Low, following the steps
below:
1 From the printer control panel, press Select
(√) to access the menu.
2 Navigate down the menu to CONFIGURE
DEVICE and press Select (√).
3 Navigate down the menu to RESETS and
press Select (√).
4 Navigate down the menu to POWERSAVE
and press Select (√).
Just prior to the 59.E0 error, a 41.19
secondary transfer high voltage error posts in
the event log. The error is most likely to occur
from trays 2 and 3 since the media moves
fastest to registration from these trays. However,
if these mechanisms are not working at any
speed, the error occurs from all trays.
5 Navigate down the menu to LOW and press
Select (√).
Note
Because the Low setting does not meet Blue
Angel energy-saving requirements for Germany,
this is a temporary workaround.
