Oki 56801 manual Display shows a communication error. This alarm

machine may be using the wrong dialing method (pulse or tone) for your area. If you hear changing tones instead of dialing pulses and you know that your area uses pulse dialing, refer to the MF(TONE)/ DP(PULSE) dial parameter setting in Programming. If your fax machine is connected to a PBX, make sure you have instituted the correct programming to work with a PBX (see Connecting to a PBX in Instal- lation).

￿The display shows a communication error. This alarm

indicates any of a number of problems. You may be trying to communicate with an incompatible fax machine (your machine can only communicate with ITU-T Group 3 fax machines). The remote machine may not be able to perform the function that you want, such as polling or confidential messages. The remote machine may also be out of paper or experi- encing a paper jam. Bad telephone line conditions can also cause communication errors. Try sending the fax again and check to make sure you are dialing the correct telephone number. If you have to dial an access digit to get an outside line, or if you are dial- ing internationally, you may need to enter a pause (using the Pause One-Touch key) after the access digit or international dialing code to tell your

machine to wait for a dial tone. If you have frequent problems communicating with a particular remote fax machine, try programming the number into one of your One-Touch keys and then changing the One- Touch Parameters for that One-Touch key (see “Dial Directories” on page 29). Lastly, either your fax machine or the remote fax machine may need servic- ing. Try sending a fax to another location to check your machine.

￿You sent a fax but the image the remote fax machine

received was very poor. If your document had a lot of small type, complex illustrations, photos, or was very light or very dark, try changing your Transmit Reso- lution and Type of Original settings (see “Loading Documents” on page 34 in Basic Operations). Copy the document on your fax machine to see how it will transmit. The problem may be caused by telephone line interference. Try sending the document again later.

￿You keep getting reports you do not want. Check

your user function settings and turn off the reports you do not want. See “Customizing Features & Operations” on page 53.
