E18
Canon Printer
Severity:What Does This Error Mean?
Error E18 on a Canon printer means a paper jam has been detected. Paper is stuck somewhere inside the printer and is blocking the print path. You need to carefully remove all jammed paper before the printer can work again.
Affected Models
- Canon PIXMA MG2522
- Canon PIXMA MG3620
- Canon PIXMA TR4520
- Canon PIXMA TS3320
- Canon PIXMA MX490
Common Causes
- A sheet of paper got caught on a roller or guide inside the printer
- The paper used is too thick, too thin, or damp and did not feed properly
- Multiple sheets of paper were fed at the same time (multi-feed)
- A torn piece of paper from a previous jam was left inside the printer
- The paper guides in the input tray were not adjusted to the paper size
How to Fix It
-
Turn the printer off immediately. Do not try to feed more paper while a jam is present.
Trying to print over a jam can worsen the blockage and damage internal rollers.
-
Open all printer covers — the front cover, rear cover, and the access panel if your model has one.
Canon printers often have a rear access door that is easier to use for clearing jams.
-
Gently pull out any jammed paper. Use both hands and pull slowly toward you, not sideways.
If the paper tears, carefully remove every scrap — even a tiny piece can cause the error to return.
-
Shine a flashlight inside the printer to check for any remaining paper scraps or debris.
Check near the rollers, in the paper path, and near the output tray area.
-
Close all covers, power the printer back on, and try printing a test page.
If E18 comes back immediately, there is still paper stuck inside that you missed.
When to Call a Professional
If you removed all visible paper and the E18 error still appears, a small scrap may be stuck deep inside. Do not force paper out — this can damage the rollers. A technician can safely open the printer and clear hidden jams for around $40 to $70.
Frequently Asked Questions
How do I prevent paper jams on my Canon PIXMA?
Use only paper within the weight range specified in your printer manual. Fan the paper stack before loading to separate the sheets. Make sure the paper guides in the input tray fit snugly against the paper edges.
The paper looks clear but E18 keeps coming back. What is wrong?
There is almost certainly a tiny scrap of paper still inside. Use a flashlight and look carefully near the rollers and paper path. You can also try running a piece of paper through manually — it may push the hidden scrap out.
Can E18 damage my Canon printer?
A single jam will not damage the printer if cleared properly. Forcing jammed paper out too quickly can bend the paper guides or damage the rubber rollers. Always be gentle and patient when clearing paper jams.
