Seaory S25 / S26 / S28 Error 48 (Ribbon Error): Fix It in 5 Steps
Seaory support · Ribbon errors

Updated October 9, 2026

Error 48 means the printer cannot read the ribbon. It is the most common error we see on the Seaory S25, S26 and S28, and it is almost never a dead printer. In our support records it came down to the same handful of causes again and again: a ribbon seated wrong, a worn ribbon gear, a ribbon LED that needs calibrating, or an LED bracket knocked out of place.

Quick answer

Work in this order and print one card after each step: 1 reseat the ribbon, 2 check the ribbon gear for missing teeth, 3 calibrate the ribbon LED with the ribbon out and the cover closed, 4 clean the LED and sensor, 5 check the LED bracket. If the ribbon is also tearing, the tear is causing the error, so go to the ribbon keeps breaking guide.

The full walkthrough. The calibration numbers in the video are one printer's readings, not a target.

Fix it in this order

1
Reseat the ribbon

Turn the printer off, open the cover and lift out the ribbon cartridge. Check three things:

  • It is the right ribbon: 11011 for the S25, 17031 for the S26 and S28. They are not interchangeable.
  • The ribbon is not torn, twisted or wrinkled, and the leader is seated in its loop on the spool.
  • It is snug, not tight. Over-tightening the ribbon before you close the cover causes tears and Error 48.

Seat the cartridge flat in its guides and close the cover gently. Never force it: a forced cover is the most common way the LED bracket in step 5 gets bent.

2
Look at the ribbon gear

The plastic gear on the end of the ribbon spool drives the ribbon. If teeth are missing or the gear is cracked, the printer loses track of the ribbon and throws Error 48, and the ribbon often tears too. A worn gear is cheap to fix: replace it with a 16300 ribbon gear, or in a pinch move the gear over from a used ribbon core.

3
Calibrate the ribbon LED

Take the ribbon out and close the cover first. Calibrating with the ribbon in gives a false reading.

When it finishes, reinstall the ribbon and print a test card. If calibration says it failed, run it once more. Two fails in a row point to step 4 or 5. Full guide: How to calibrate the ribbon LED.

Calibration reading What it means
Around 195 Normal. Reinstall the ribbon and print.
Fails, but reads above 50 The LED or sensor is dirty or slightly out of line. Steps 4 and 5.
Reads 0 The sensor or its cable has a fault. Contact us; this is not a cleaning job.
4
Clean the LED and sensor

With the printer off and unplugged, wipe the ribbon LED and the sensor below it with a dry or lightly alcohol-dampened swab. Let them dry fully, then calibrate again with the ribbon out and the cover closed.

5
Check the ribbon LED bracket

The LED sits on a small plastic bracket. If it has been pushed out of its notch, the LED points at the wrong spot and calibration keeps failing. With the power off, compare yours to the photo. If it is just out of its notch, press it gently back in place. If it is bent, cracked or loose, stop. It is a replacement part, and we will send it with a video showing the swap.

Error 48 together with a torn ribbon

If the ribbon is tearing mid-print, the tear is what triggers Error 48, and calibrating again will not stop it. Follow Ribbon keeps breaking. It covers the print position, design and tension fixes that solved most of these cases.

Other ribbon codes on the S25, S26 and S28

Code What it means What to do
41 or 46 Ribbon used up; the roll and its count disagree by a print or two Fit a new ribbon
43 No ribbon found: not installed, or loaded backwards Match the colored spool ends to the colors on the cartridge
44 Ribbon not supported (made for a different region) Use ribbons from Bodno for your printer
45 Ribbon missing, often after a tear or a ribbon that rewound Error 45 guide
49 Ribbon dragging or slipping Check the gear (step 2), confirm the ribbon matches your model, recalibrate (step 3)

Which step fixes what

What you see Most likely cause Go to
Error 48 right after a ribbon change Ribbon seated wrong or too tight Step 1
Ribbon slips or tears, gear looks chewed Worn ribbon gear Step 2
Error 48 on a new ribbon, ribbon looks fine LED needs calibrating Steps 3–4
Calibration fails every time LED bracket out of place or damaged Step 5
Error 48 after the ribbon tears mid-print Print position, design or tension Broken ribbon guide
Ribbon winds backwards when you close the cover Ribbon motor Error 45 guide

Questions about this

01 Does Error 48 mean the printer is broken?
Rarely. In our support cases it came down to ribbon seating, a worn ribbon gear, the ribbon LED calibration or the LED bracket.
02 Can I calibrate with the ribbon installed?
No. Take the ribbon out and close the cover first, or the reading will be wrong.
03 What is the difference between Error 48 and Error 45?
Error 48 means the ribbon LED cannot read the color panels. Error 45 means no ribbon is detected, often because a ribbon motor is not turning. Use the Error 45 guide for that one.
04 The ribbon is also torn. Which do I fix first?
The tear. A torn ribbon triggers Error 48, so follow the broken ribbon guide first.
