❏ Print quality poor?
• Are you using the correct type of paper?
Be sure you are using paper that meets the paper requirements for this fax.
See p. 7.
• Is the fax unit’s BJ cartridge out of ink?
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?
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.
• Is your fax set for ECM receiving?
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?
ECM sending/receiving should eliminate such problems. However, if the
telephone lines are in poor condition, you may have to try again.
• How is the quality of the other party’s fax?
Remember, the sending fax usually determines document quality. Be sure
the other party’s back of top cover and scanning glass are clean.
