32 Chapter 1 Troubleshooting control panel messages
EN
The print engine is not communicating with the formatter. The
communication link between the formatter and DC controller was lost.
This can occur due to a timing error or intermittent connection between
the formatter and the DC controller.
1 Turn the printer off and on to reset the printer.
2 Reseat the connectors between the formatter and DC controller.
3 Only if the error persists, replace the DC controller making sure to
perform the calibration and color plane alignment procedures.
The printer detected that the fan (an exhaust fan located in the upper,
left-rear corner of the printer) was not rotating. This fan operates off
+24 Vdc and is enabled by the DC controller PCB’s microprocessor.
1 Turn the printer off and on to reset the printer. Visually check to see
if the fan is rotating. (If you cannot see any rotation, place your hand
over the outlet vents to see if exhaust air is moving).
2 Remove the printer’s left-side cover. Check to see if anything is
preventing the fan from rotating freely.
3 Verify that the fan’s connector is firmly seated into connector J208 of
the developing PCB.
4 If the error persists, replace the fan.
