Do not press START/COPY after you hang up the telephone; this will disconnect the call. Be sure you are using paper that meets the paper requirements for the MultiPASS (see page A-1). Clean the print head (see page 9-8). Make a copy on your MultiPASS. If the image is OK, then your MultiPASS is operating properly. Contact the other party and have them check their machine. Make sure Error correction (ECM) is set to on in the Advanced: Receive fax dialog box of the Desktop Manager. Be sure to remove the orange tape from the BJ cartridge before you install it in the MultiPASS (see page 9-14). Make sure the BJ cartridge is installed correctly (see page 9-11). Clean the print head several times (see page 9-8). Try another BJ cartridge. 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 top cover and scanning glass are clean. Chapter 10
