Adjusting the Transfer Belt Offsets
The Transfer Belt Offset only needs adjustment in cases where the Transfer Roller Bias adjustment has
reached its limit without resolving the problem.
Adjusting the Transfer Belt Offset for black (K) or color (YMC) requires entering Service Mode and
editing NVM using a specific Chain-Link code. Refer to “NVM Read and Write (Edit NVM)” on page 2-28
for detailed instructions on editing NVM values. Refer to the table below for the Chain-Link codes
associated with each offset adjustment.
To adjust the Transfer Belt Offset:
1.
Enter Service Mode and navigate to Printer Diag > Engine Diag > NVM Settings > Edit NVM.
2. Enter the Chain-Link code (see the table) for either K or YMC Offset.
CAUTION: In the following step, do not use values higher than 11.
3. Adjust the value up or down as necessary to a value with the range 1-11. The default setting is 6.
Adjusting Altitude
Print quality varies with barometric pressure. Since the barometric pressure decreases as the altitude
increases, altitude can affect the print quality. To optimize print quality for your location, select an
altitude setting to match the your location.
Adjusting for altitude requires entering Service Mode and editing NVM using a specific Chain-Link
code. Refer to “NVM Read and Write (Edit NVM)” on page 2-28 for detailed instructions on editing
NVM values.
To adjust altitude:
1.
Enter Service Mode and navigate to
Printer Diag > Engine Diag > NVM Settings > Edit NVM.
2. Enter Chain-Link code 746-515.
3. Set the value to 1000, 2000, or 3000, whichever is closest to your altitude in meters. The default
setting is 0. Use
only the NVM values listed in the following table.
Parameter Range Initial Chain Link
K Offset 1~11 6 746-516
YMC Offset 1~11 6 746-517
