Blur or bands: choose the right head alignment

The ET-8500 guide offers two alignment modes. Bands can also mean nozzle cleaning is needed.

1. Resolve LCD errors; remove the CD/DVD tray if inserted for printing.
2. Put several plain sheets in lower Cassette 2.
3. From Home, open Maintenance → Print Head Alignment.
4. Choose Vertical Alignment for blur or misaligned vertical lines; Horizontal Alignment for horizontal bands.
5. Print the alignment sheet as prompted, without cancelling the pattern print.
6. Enter the number with the smallest gap or overlap: for each vertical set, or the horizontal pattern.
7. Finish using the remaining panel prompts.

Compare the nozzle pattern and cleaning limits before assuming alignment is the cause. Common PC check: when device output is clear but PC jobs fail, compare this model’s driver setup.

Rear paper sources and blank sheet ejection

The ET-8500 has a rear paper feeder for stacks of supported paper and a rear paper feed slot for a single sheet of specialty stock. To locate either source, open LCD Help and choose How To → Load paper, then select its illustration.

• Rear Paper Feeder. Load up to 50 sheets of plain Letter or A4 paper. Photo-paper capacity varies by paper type.
• Rear Paper Feed Slot. Load one sheet at a time. For thick paper or card stock 0.61–1.3 mm thick, check the ET-8500 sizes in the loading-capacity table, including Letter, A4 and Legal. The table lists A3 and A3+ for the ET-8550 only.

Select the slot from a computer

1. In the Epson Windows print settings, set Paper Source to Rear Paper Feed Slot. In the Epson Mac print settings, choose the compatible slot option under Paper Size. The Mac Rear Paper Feed source selects the feeder.
2. Send the print job first. When the printer prompts you to load paper, insert one sheet short edge first with the printable side up. If the slot ejected an early-loaded sheet blank, try the steps in this order.

If the slot choice is missing from the Epson print settings, check the selected printer and paper size, then use the ET-8500 printer driver guide to check your setup. Epson’s illustrated loading steps · Epson’s paper-feed FAQ

Ink on the back: paper-guide cleaning and two white rollers

The exact ET-8500/ET-8550 guide starts with paper-guide roller cleaning for ink on the back. This uses the rear feeder, separate from the lower-cassette nozzle test above.

Start with the control-panel cleaning

1. Clear LCD errors and make sure the CD/DVD tray is not inserted for printing.
2. Load Letter or A4 plain paper in the rear paper feeder.
3. Open Home → Maintenance → Paper Guide Cleaning and follow its screen prompts.
4. Repeat as needed until the paper comes out clean. If ink smears persist, use the powered-off follow-up below.

If ink still appears: disconnect power before roller care

Do not use tissue on the rollers: lint can clog the print-head nozzles. Use the illustrated roller locations; opening the scanner unit for internal Paper Path cleaning is a separate documented procedure.

1. Switch off. Unplug the power cord from the outlet and disconnect it from the printer; disconnect other cables.
2. Gently pull out the output tray. Locate the two white rollers using the official illustration linked below.
3. Moisten a cotton swab with a little water, wipe those two rollers and rotate them gently to clean around them.
4. Reconnect the power cord and interface cables after completing the procedure.

Official HTML and illustrations checked 21 October 2026; final editorial verification 22 October 2026. Earlier 14 October diagnostics, 16 October software and 18 October scanning evidence retains its dates. No printer cleaning, printing, installation or settings change was performed.

Inspect the translucent film after alignment and paper path cleaning

If print quality is still poor after head alignment and paper path cleaning, Epson recommends checking the internal translucent film for ink smears. Clean it only if you can see ink on the film.

1. After the printer finishes its current operation, switch it off and unplug the power cord and other cables. Lift the scanner unit and use a small flashlight to locate the translucent film (1) in Epson's diagram. Leave the adjacent print head rail (2) and its grease alone.
2. Mix 59 mL of water with 2–3 drops of mild dish detergent. Dampen a cotton swab, squeeze out excess liquid, and lightly wipe only the ink marks. Other cleaners or pressure on the film can damage the printer.
3. Dry the film with a fresh, dry swab. Check that it is dry and free of fibers before lowering the scanner unit, reconnecting the cables, and switching on.

As a general check, if the printer's own output is clean and the problem only occurs in computer jobs, compare the app's paper type and quality settings and check the official ET-8500 driver.

When photos look off-color or print in grayscale

Start by matching the print dialog’s media type to the paper you loaded. If a color photo comes out gray, check the selected ET-8500 print settings and clear Black/Grayscale or Grayscale. If the Epson driver shows a color mode, try EPSON Standard for a comparison print.

If one color is missing or the print has bands, run the printer’s nozzle check and look at the ink levels in the tanks. If the pattern has gaps, follow the cleaning steps for the pattern.

With a complete nozzle pattern, compare the same file on the same paper. Let the prints dry without stacking them before judging color. If the Windows driver offers the controls, compare Color Management and Scene Correction under More Options one change at a time. When printing a photo directly from the panel, compare Auto and Enhance Off if Fix Photo is available.

If you cannot find the Epson print settings or only computer jobs fail, check the ET-8500 driver guide for your operating system and print component.

CD/DVD tray: wait for loading prompts, remove after printing

Computer text/image designs use Epson Photo+. Keep this separate from panel copying and check components for your actual OS. Official feature overview

1. Use compatible inkjet-printable CD/DVD/Blu-ray media; record data first.
2. Close Output Tray if needed; retrieve the disc tray beneath lower Cassette 2.
3. Wait for the loading prompt. Follow its animation and seat the disc fully. Never insert during other operations.
4. After automatic ejection, remove tray and disc. Select Printing Complete; store the tray beneath Cassette 2.

Remove disc and inserted tray before power-off or head cleaning. Drying may take up to 24 hours; avoid moisture and direct sun. Loading, removal and diagrams

Official disc troubleshooting · Existing nozzle test · This ET-8500 driver guide

Common host comparison: if device output works but PC jobs fail, compare the selected ET-8500 queue, application settings and same-model driver. These symptoms are not new numeric error codes.

Disc checks verified 24 October 2026 from four sections linked by the ET-8500/ET-8550 HTML guide. Earlier software and diagnostic dates remain; current Photo+ OS compatibility, physical printing and settings changes were not tested.

If printing works but computer scanning fails

1. Check the selected Epson Scan 2 file against the computer’s actual OS and CPU conditions. The print-driver list and scan-driver list are different; an installed print queue is not a scan test.
2. For a task using ScanSmart, Event Manager or OCR, compare the separately named components in the Mac download table and combo description. The print driver alone is not evidence that these components are installed.
3. Keep the existing USB/network and selected-computer checks above. For software selection return to this ET-8500 printer driver download guide; compare scanning separately after any approved installation. These are common software checks, not a newly verified device repair sequence.

Scan from the ET-8500 panel to a computer

The manual’s panel-to-computer workflow calls for Epson Scan 2, Epson ScanSmart and Event Manager. A working print queue alone does not verify those components. Compare their OS conditions in the separately dated print/scan file table. Official panel workflow

1. Place the original, then select Home → Scan → Computer. Close the information screen with OK if it appears.
2. For a direct USB host choose USB Connection. For a network host choose Select a computer and the intended computer; use Search Again if it is absent. The host must use the product’s network.
3. Open the current scan-action field (Save as PDF in the text; Preview on Computer in the example) and choose ScanSmart preview/editing, JPEG or PDF. The selected action and connected computer are separate choices.
4. Use the documented Send/Save icon to begin. Confirm the resulting file on the intended computer; a PDF choice does not itself establish editable OCR text.

Compare a missing PC or panel-only failure

Event Manager’s Make Job Settings → Edit Job Settings controls the assigned scan action. Record the existing job before changing it; this differs from replacing the print driver or starting a firmware tool. Official Event Manager controls If a scan component is absent, use the same ET-8500 download guide and select the actual host conditions.

Verified 18 October 2026 from the ET-8500/ET-8550 guide and its linked panel/job/network pages. These are the manual’s English control names; actual UI/OS versions may differ. The network paragraph’s additional USB-labelled selector note does not replace its main USB-versus-network branches. Earlier 14 October device diagnostics and 16 October software-version/OS scopes remain unchanged. No installer, scan job, firewall/router change, scanner reset or physical device action was run.
