Print Quality Notice

Printers are shipped with three different carrier transport motors displaying a label which reads either NMB(NMB), Airpax(APX) or Mitsumi(MZM). The label on the motor should match the motor ID in NVRAM. To verify the motor ID stored in NVRAM, print out a Test Page. The three letter designation will be printed on the service line.

If the carrier transport motor or the system board must be replaced, check the label on the carrier transport motor. All FRU motors will be labeled NMB.

After completing repairs to the printer, connect it to a PC and go to x:\Tools\4078 (where x is the letter of your CD-ROM drive) on your latest Service Information and Training CD-ROM and perform one of the following commands to download the file to your printer. Use the file that matches the transport motor label.
