How to clear the PB00 problem in canon G2000 pixma printer

Author's note: Canon's newer printers have modular pads and clear, actionable errors - if you choose to replace the printer, look for one with a replaceable waste ink pad (maintenance cartridge). DO NOT BUY ONE WITH A SEALED PAD - they're becoming history for good reason. Some models with features like CD printing only come this way like the TS702a (no choice) unless you buy an Epson. But for most people you have a choice - use it. If there is no documented part starting in "MC" don't buy it.

I'm going to work under the assumption it's the 5B00 code, which is a waste ink error code - the last number varies, but it's always 5B0X in some flavor as it's a common code with Canons. The final number depends on HOW full the pad is and even series in some cases as each machine gives little variations of this error. If the pad is saturated and locked out, it is nearly full, and you always need to intervene to print.

First, you'll need to replace the pad. The pad on this series is built into the base, so you'll need to wear gloves, as it isn't quarantined in a module like the MG and others with smaller pads. The pads aren't expensive and are readily available, so you can do it for $15-$ 25. Just make sure to clean the base before installing them, as you'll fill them up with ink from the base that stuck around. It doesn't need to be perfect, but you do need to get the majority up. You will need to do a complete teardown. It won't be a quick fix :-(.

The other issue is resetting the counter; this printer performs the lockout via firmware. Use a tool like WIC (https://www.wic.support/download/) or, if available, the Canon Adjustment tool v3400 or v4905 (not linking it to avoid making a DMCA takedown easy for Canon's lawyers; if it's available, it will appear on the first or second page of Google). It will need to be put into service mode, and for this panel, it's done as follows:

• Turn off the printer
• Hold down the “Stop” button
• While holding “Stop”, press and hold the “Power” button
• While holding “Power”, release the “Stop” button, then press it 5 times
• Release both buttons. The printer should be in Service Mode (no error display)

You may be able to avoid the tool route for the G2000, but it's not guaranteed to work:

• Press STOP 5 times, then press POWER once, and let the printer print a status sheet.
• Press STOP 3 times, then press POWER once. The printer will print another sheet showing “D=000.0”.
