Sony UP-21MD
Sony · Model UP-21MD
Two different print packs may be used with the UP-21MD. The UPC-21S colour print pack contains 3 rolls of ink ribbon and S-format print media (100mm x 90mm) for 240 prints. The UPC-21L colour print pack contains 4 rolls of ink ribbon and print media in L format (144mm x 100mm) for 200 prints. The choice between large-format L and small-format S allows for more flexibility and gives two cost options. Short print times in A6 format. Compact dimensions. Front control panel. Versatile analog/video inputs and outputs. RS-232C Connector.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Poor print quality
HighSymptoms: Density too light / dark, banding, streaks, non-uniform image, blotches.
Root cause: Print head / laser optics contamination, film / cartridge issue, or density-calibration drift.
Film jam / transport fault
MediumSymptoms: Film jams in the pick-up or transport, mis-feeds, or multi-feeds.
Root cause: Worn pick-up rollers, a transport-roller fault, or a mis-loaded film cartridge.
Density / calibration fault
MediumSymptoms: Prints do not match the reference, calibration fails, densitometer error.
Root cause: Internal densitometer or the calibration routine.
DICOM / queue fault
MediumSymptoms: Jobs stuck in the queue, printer offline to modalities, association failures.
Root cause: Network / DICOM configuration or the controller board.
Thermal head / laser fault
MediumSymptoms: Whole-image defect, print-engine error.
Root cause: Thermal print head or the laser / optics module.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Poor print quality (banding, streaks, light / dark, blotches)
- Print the built-in test / SMPTE pattern.
- Run the density calibration.
- Clean the print head / laser optics per the manual.
- Confirm the film type / cartridge matches the printer setting.
- Replace the print head or optics module if a whole-image defect persists.
Symptom: Film jam / mis-feed / multi-feed
- Clear the jam and note the location.
- Inspect and clean the pick-up and transport rollers.
- Confirm the film cartridge is loaded correctly.
- Cycle several sheets.
- Replace worn rollers as found.
Symptom: Jobs stuck in the queue / printer offline to modalities
- Check the DICOM association and the network link.
- Restart the print controller / spooler.
- Confirm the modality print settings (AE title, IP, port).
- Send a test job.
- Escalate a controller-board fault to the OEM.
