Canon printers display two very different kinds of errors: a numbered "Support Code" on models with a screen, like 5B00 (waste ink absorber full) or B200 (a print head or power circuit fault), and a blinking orange Alarm lamp pattern on simpler models without one. Both types point to specific, well-documented causes rather than a generic "something's wrong," and most can be narrowed down in under five minutes before you decide whether to repair it yourself or call a technician.
What Does Canon Error 5B00 Mean, and Can You Fix It Yourself?
Error 5B00 means the printer's internal waste ink absorber pads have reached their counted capacity, a safety limit Canon builds in to prevent ink from overflowing inside the unit, even though the pads usually still have physical room left. This is one of the most common errors on long-used Canon PIXMA printers and doesn't mean the printer itself has failed.
A professional service resets the internal waste ink counter and, where needed, replaces the absorber pads, which is covered under a standard multifunction printer repair visit and typically restores years of further use rather than requiring a new printer.
What Does Canon Error B200 Mean? Is It Repairable?
Error B200 is a more serious fault, usually pointing to the print head overheating or a short circuit somewhere in the print head's power supply, and it's well known among Canon PIXMA owners as one of the trickier codes to resolve. Unlike 5B00, it genuinely stops the printer from working until the underlying electrical issue is fixed.
- Error appears immediately on power-on, every time: this points to a persistent short or a failed print head, which needs inspection rather than repeated restart attempts.
- Error appears only occasionally, often after printing for a while: this suggests an overheating issue rather than a dead component, sometimes resolved by letting the printer rest and cool before the next print job.
Because B200 can stem from several different internal causes, a technician needs to test the print head and power board separately to confirm which one is actually at fault before quoting a repair.
Canon Support Code 6000 and Other Paper Jam Codes
Support code 6000 and similar paper-related codes usually mean exactly what they say: paper is stuck somewhere in the feed path. But a jam code that returns immediately after you've cleared all visible paper points instead to a dust-blocked sensor along the path rather than an actual obstruction.
Reading the Alarm Lamp Blink Pattern on Simpler Canon Printers
Entry-level Canon printers without a screen use an orange Alarm lamp combined with the green Power lamp to signal faults, where the number of alternating blinks before the pattern repeats identifies the specific issue, similar in concept to Epson's blink codes but with Canon's own pattern meanings. Counting the blinks carefully, rather than guessing from a single glance, gives a technician useful information before they even arrive.
Quick Fixes to Try Before Booking a Repair
- Power cycle at the printer's own switch, not the wall socket, and wait a full thirty seconds before switching back on.
- Open the printer and check the carriage path for stuck paper, torn label remnants, or small foreign objects before assuming an electrical fault.
- Count the blink pattern or note the exact support code before calling, since this single piece of information often tells a technician what parts to bring.
A Technical Note: Why the Same Error Code Can Have Multiple Causes
Canon's error codes describe which subsystem detected the fault, not always the single root cause behind it, which is why two printers showing the same code can need completely different repairs. A printer repair visit always includes a hands-on test of the suspected component rather than replacing a part based on the code alone, which avoids paying for a fix that doesn't address the actual fault.
