❏ Print quality poor?
Are you using the correct type of paper?
Is the fax unit’s BJ cartridge out of ink?
Be sure you are using paper that meets the paper
requirements for this fax. See p. 7.
Replace the BJ cartridge. See p. 105.
Make a copy on your fax. If the image is OK,
then your fax is operating properly.
Contact the other party and have them check
their machine.
❏ Cannot receive using Error Correction Mode (ECM)?
Does the other party’s fax support ECM?
Is your fax set for ECM receiving?
Some fax units do not support ECM
transmission. If the other party’s fax does not
support ECM, the document is sent in the
normal mode without error checking.
ECM receiving can be turned off and on. Check
the current setting. See p. 87.
❏ Nothing prints?
Did you remove the orange tape from the BJ
cartridge before you installed it in the fax? Be sure to remove the orange tape from the BJ
cartridge before you install it in the fax.
See p. 11.
Make sure the BJ cartridge is installed correctly.
See pp. 11–13.
Clean the print head several times. See p. 104.
Try another BJ cartridge.
❏ Are the images you print blotched or uneven?
Are you using ECM sending/receiving?
How is the quality of the other party’s fax?
ECM sending/receiving should eliminate such
problems. However, if the telephone lines are in
poor condition, you may have to try again.
Remember, the sending fax usually determines
document quality. Be sure the other party’s back
of top cover and scanning glass are clean.
