If you own a Canon printer and suddenly see Error Code 5B00 on the screen or your printer stops working with flashing lights, it can be frustrating. Many Canon printer users face this issue after extended use, and it can appear unexpectedly. Fortunately, this is not a fatal error and can usually be fixed with the proper steps. This blog will explain what Canon Error 5B00 means, why it happens, and how you can safely reset it and get your printer back to normal.
Understanding Canon Error Code 5B00
Canon Error Code 5B00 refers to a problem related to the printer's waste ink absorber. Inside every Canon printer, there is a component known as the waste ink pad or absorber. During printing and maintenance operations, such as print head cleaning, a small amount of excess ink is flushed out to maintain print quality. This ink is collected in a sponge-like pad located at the base of the printer. Over time, the pad becomes saturated.
When the printer's internal system detects that the ink absorber is nearly full or believes it has reached its maximum capacity, it triggers Error Code 5B00. This is a built-in safety mechanism that prevents ink from leaking inside the printer, which could damage the internal electronics.
Why This Error Occurs
This error occurs mainly due to prolonged printer use without servicing or resetting the internal waste ink counter. Every time you perform a cleaning cycle or cancel a print, some ink is sent to the absorber. Over time, this ink accumulates, and the printer logs this information in its memory. When the counter reaches a predefined limit, the system turns off the printer to avoid further use until maintenance is performed.
Even if the ink absorber is not physically full, the counter may reach its limit due to years of operation. This is why some users might see the error despite no visible signs of ink overflow. It's the printer's way of indicating it's time for maintenance or a counter reset.
Is Canon Error 5B00 a Serious Issue?
While the error might seem alarming at first, it's not always a severe hardware failure. It's more of a protective warning. Canon includes this feature to prevent users from continuing to print when there's a risk of internal ink leakage. However, ignoring the issue and repeatedly attempting to print can lead to real damage.
If you encounter the 5B00 error, please stop using the printer and take steps to either reset the waste ink counter or service the printer to clean or replace the waste ink absorber pads.
How to Reset Canon Error Code 5B00
Resetting this error involves entering a special service mode on your Canon printer and using either manual or software-based methods to reset the waste ink counter. Here's a step-by-step guide on how you can do that:
Step 1: Enter Service Mode
First, you need to enter service mode on your Canon printer. This process can vary slightly depending on the model, but a standard method for many Canon PIXMA printers involves holding down a combination of buttons. Start by turning off the printer. Then press and hold the Stop or Reset button, followed by the Power button. Keep the Power button held down while you press the Stop/Reset button five times. After this, release both buttons. The printer should now be in service mode. Although the screen may remain blank, it's ready for the reset process.
Step 2: Use a Canon Service Tool to Reset the Counter
After entering service mode, you need the Canon Service Tool software to reset the internal counter. This software connects to your printer and allows you to reset the waste ink absorber data. Once installed and opened, the tool will detect your printer model and display several options. You will need to select the function related to the ink absorber counter, typically labeled "Main" or "Platen." Click "Set" to reset the counter. In most cases, this action will result in a test print or EEPROM print confirmation that shows the counter has been reset to zero.
Please note that Canon Service Tools are not publicly available and are intended for use by service technicians. However, many users have found ways to use them at their discretion. Be cautious when downloading software from third-party sources, and always ensure it is compatible with your printer model.
Step 3: Clean or Replace the Waste Ink Pads (Recommended)
Resetting the error code will stop the alert and allow your printer to function again, but it does not physically remove the ink from the pads. If the pads are truly saturated, they will continue to collect ink and may eventually overflow, causing internal damage.
To fully resolve the issue, it is recommended to either clean or replace the waste ink absorber pads. Cleaning involves opening the printer, locating the pads (which typically appear as small, sponge-like components), and rinsing them under warm water until they are clean and dry. Allow the pads to dry entirely before reinserting them. Replacing the pads with new ones is the better option if they are worn out or degraded.
Opening the printer may void your warranty if it is still active, so consider consulting a Canon service center for professional support.
When to Seek Professional Help
If you are uncomfortable entering service mode, using unofficial tools, or opening the printer to clean the pads, it's best to take the printer to a certified Canon technician. They can safely perform the reset using official software and check if any other maintenance is needed. This is especially advisable if your printer is still under warranty, as unauthorized repairs may affect coverage.
Professional servicing not only ensures proper repair but also helps in safely disposing of the waste ink collected in the printer.
Preventing Error Code 5B00 in the Future
While you can't entirely avoid the build-up of waste ink, you can delay the error by maintaining your printer correctly. Avoid running excessive head cleaning cycles, which generate large amounts of waste ink. Use the printer regularly to prevent clogs that lead to maintenance flushing. If you print in high volumes, schedule regular maintenance or service visits to clean the ink system before problems arise.
Some advanced models may also allow you to check the ink absorber counter status or receive early warnings. To ensure optimal performance, keep your firmware up to date and refer to the printer's manual for maintenance tips.
Conclusion
Canon Error Code 5B00 is a standard error that occurs when the printer's waste ink absorber is full or its counter has reached the limit. While the printer stops working when this error appears, the issue is typically solvable. By entering service mode, resetting the waste ink counter using Canon's service tools, and cleaning or replacing the waste ink pads, you can revive your printer.
However, this process requires care. If you're not comfortable with DIY solutions, it's always safer to consult a professional technician. In the Future, adopting good maintenance practices will help reduce the frequency of such issues and extend the life of your Canon printer.
