IQ20 1st BTR Checkout RAP

Procedure
Make a copy of the Color Test Pattern. If the high density gradation patches (100%, 85%, and
70%) for one or more of C, Y, M, or K appear to be light, perform the following:
• Refer to Figure 1. Check the wiring between the BTR1 HVPS
on the Drum Cartridges.
• Check the 1st BTR Monitor values as follows:
Do not allow the IBT to run longer than 10 seconds. Damage to the Transfer Belt may
occur because the automatic belt-walk adjustments are not performed while in dC140.
1. Enter dC140 [009-200]. Press Start. The monitor value should be low (typically 0 - 3)
2. Enter [009-051]. Press Start. After a few seconds, the value should jump signifi-
cantly.
3. Press Stop All.
NOTE: Do not enable more than one color at a time. Attempting to run more than one monitor
without clearing the previous code may cause the PWS to lock up.
4. Repeat steps 1 through 3, using 009-201, 009-202, and 009-203 as the input code.
If the value fails to increase significantly for one or more monitor codes, replace the BTR1
HVPS (PL 9.1).
• Refer to Figure 1. Check the connectors and wires shown for damage, contamination, or
loose connections.
