dC625 Registration / Preheat Calibration (RaLPH)
Purpose
To manually initiate calibration of the registration / preheat assembly with the rest of the print
engine.
Initial Action
Perform the following procedures:
• dC971 Head to Head Alignment Adjustment.
• dC977 Drum Runout Calibration.
• Ensure no missing black jets with jet substitution routine.
• Ensure the IME is ready to print by exiting service mode.
NOTE: Switch off, then switch on the machine, GP 14.
NOTE: The dC625 Registration / Preheat Calibration procedure is required after replacing,
removing or reinstalling:
• Registration / preheat assembly
• Horizontal paper path
• IOD sensor
Procedure
NOTE: If dC625 is run directly after the machine is switched on, a cleaning unit pump diagnos-
tic cycle may run during calibration. After printing several calibration printouts, the machine
may raise a cleaning unit communication error instructing the cleaning unit be re-installed.
This causes the calibration to fail. After re-installing the cleaning unit, the machine raises fault
94-532 DMU oil pump over current. If this occurs, re-install the cleaning unit, switch off, then
switch on the machine, GP 14. Make at least 20 copies then re-start dC625.
1. If performing this procedure directly after installing a new cleaning unit or switching on the
machine, make at least 20 copies before performing dC625.
2. Enter service mode, GP 1.
3. Select the Adjustments tab.
4. Select dC625 Registration / Preheat Calibration (RaLPH).
5. Follow the on screen instructions.
6. Select Start and the process runs.

LEF) as per chase sheet selection.
• The printed registration calibration pages (TP 24) are fed back through the registra-
tion / preheat assembly via the duplex paper path.
• Registration image is read by the CIS scan bar located on the registration / preheat
assembly:
• The adjustment is made automatically after 30 successful scans are analyzed.
