Start with the simplest reversible checks: confirm the correct media, sensing mode, loaded path, print setting, and calibration before changing advanced settings or replacing parts.
Short answer
For banding, run the approved nozzle check and cleaning process, then confirm print mode and media. For smudging, verify inkjet receptive stock and drying conditions. For skipped labels, confirm gap or black mark sensing and calibrate. For alignment, check label dimensions, sensor position, feed direction, and artwork margins.
Change one variable at a time and keep a known-good sample.
Many apparent printer faults are media or sensing mismatches.
Stop and use Epson support when the manual warns against further cleaning or disassembly.
| Symptom | First checks | Next action |
|---|---|---|
| Horizontal banding | Nozzle check, print mode, media coating | Approved cleaning and alignment procedure |
| Wet or smeared ink | Inkjet receptive media, setting, environment | Test approved stock and allow proper drying |
| Skipped labels | Gap or black mark mode, sensor position | Calibrate with the installed roll |
| Image shifts | Label size, liner width, feed direction | Correct layout and media detection settings |
| Barcode will not scan | Quiet zone, contrast, size, resolution | Verify with a barcode inspection process |
| Feed errors | Roll loading, guides, curl, OD, core | Reload and test a known compatible roll |
Use a controlled diagnostic sequence
Record the printer model, firmware, connection, media part number, label dimensions, sensing method, print mode, and exact symptom. Save one bad label and one known good label. This evidence prevents random setting changes and makes support faster.
Reproduce the issue with one file and one roll. If the symptom disappears with known compatible media, investigate the original stock. If it follows every roll and file, move to printer checks in the order recommended by Epson.
- Confirm the correct driver and printer queue.
- Restart the job only after recording the current settings.
- Do not run repeated cleaning cycles without checking the manual.
Banding and missing colour
Banding can come from blocked nozzles, an unsuitable print mode, contaminated media, head alignment, or artwork scaling. Run the model's nozzle check and compare the pattern with the reference in the manual. Use only the approved cleaning command and reassess before repeating it.
If the nozzle pattern is complete, print the same file at a recommended quality setting on known compatible stock. Inspect whether the bands align with the feed direction, a repeated design element, or a colour channel. That distinction helps separate artwork, media, and print engine causes.
Do not open the print mechanism or apply unapproved solvents. Escalate persistent nozzle or mechanical faults to Epson support or an authorized service provider.
Smudging, slow drying and poor adhesion
Pigment ink still needs an inkjet receptive surface. Thermal, laser, or uncoated synthetic stock may not absorb or bind the ink correctly. Confirm the exact material construction, not only whether the label is paper or plastic.
Check the media setting, print density, handling time, temperature, humidity, and whether labels rub against a guide or rewinder. Test the finished label after the ink has stabilized and under the real exposure, including condensation, abrasion, oil, or cleaning agents.
- Use approved inkjet media.
- Avoid touching heavy coverage areas immediately.
- Check that the printed face does not drag on hardware.
- Validate durability separately from drying speed.
Skipped labels and alignment errors
Skipped labels usually point to a sensing problem. Confirm whether the roll uses a gap, black mark, hole, or continuous mode. Verify the sensor can reach the gap or mark, then perform media detection or calibration according to the manual.
Alignment also depends on the file. The document size must match the finished label, while the printer media size must match the web and sensing interval. Include bleed where needed, keep barcodes clear of edges, and confirm the correct leading edge and unwind direction.
- Reload the roll with guides touching lightly, not crushing the liner.
- Enter the correct label length and gap.
- Check for clear liner or unusual die cuts that need special sensing.
- Test one variable, print a small batch, and document the result.

Frequently asked questions
Why does my Epson ColorWorks print horizontal lines?
Possible causes include nozzle issues, print mode, media, alignment, or artwork. Start with the approved nozzle check and a known compatible roll.
Why is the ink smearing?
The stock may not be inkjet receptive, the media setting may be wrong, or the label may be handled before it stabilizes. Test approved media first.
Why does the printer skip every second label?
Check gap or black mark mode, sensor position, label length, gap value, and calibration with the installed roll.
When should I call Epson support?
Escalate when approved cleaning and media checks do not resolve the problem, when the manual shows an error requiring service, or before any disassembly.
