TAG 026: Paper in Output Area Before Printing
Error Code: 026
Possible Defects: Exit paper sensor
PCL board
Connectors or wiring
If the printer has a high capacity output unit (HCO), unplug and remove it before begin-
ning this TAG. Test the printer without the HCO; if the problem remains, proceed with this
TAG. If the problem occurs only with the HCO, the HCO is causing the problem. Repair or
replace the HCO.
