Ribbon-related failure Troubleshooting procedure
The printout is partially printed white or the ribbon is
disengaged.
 The ribbon has excess slack.
 The ribbon is bent or folded.
 The ribbon path at the printhead is too high or too low.
 The ribbon is reversed.
1. Reinstall or replace the ribbon cassette.
2. The ribbon may bind, bend or reverse if the CARD GUIDE ASY is not adjusted
correctly. Perform the Card guide mount position adjustment (p.227)
3. Ribbon slack commonly occurs when the platen gap is too narrow, for example
if the paper or form being printed is too thick. Make sure the paper is within
specifications. If overlapping forms are being used, be sure the SelecType
setting for Overlapping Multipart Forms is set to On.
4. Use SelecType to change the settings. See Platen gap setting (SelecType) (p.10)
5. The following adjustments affect the platen gap: the Card guide mount position
adjustment (p.227), the APTC thickness detection adjustment (p.238), and the
APTC detection position adjustment (p.241).
6. A portion of the ribbon has reversed (i.e., ink-side in). Check the ribbon for a
reversed fold. Replace the ribbon cartridge if necessary.
Ribbon jam frequently occurs, or is frequently indicated. 1. Reinstall the ribbon cassette. If the cassette is defective, replace it.
2. If “false-positive” ribbon jam errors are indicated, replace the (Ribbon Feed) RF
UNIT (p.164).
3. An improperly adjusted CARD GUIDE ASY impairs the ribbon’s feed
performance. Perform the Card guide mount position adjustment (p.227).
4. A deformed ribbon MASK can cause the ribbon to jam. Check and replace the
Ribbon MASK (p.155)
5. Incorrect PRINT HEAD gap. The following adjustments affect the platen gap:
the Card guide mount position adjustment (p.227), the APTC thickness detection
adjustment (p.238), and the APTC detection position adjustment (p.241).
