Canon Pixma PRO-1: Troubleshooting and Solutions

Error 6700 and Coin Battery

Upon acquiring a barely used PRO-1 printer, you may encounter Error 6700, indicated by the resume and power buttons blinking 26 times. This error typically signifies an issue with the internal coin battery. Replacing the battery might seem like a straightforward fix, but in some cases, the error persists even after battery replacement.

To resolve Error 6700, follow these steps:

1. Disconnect the power plug and remove the coin battery.
2. Allow the printer to sit for a few seconds.
3. Reconnect the power plug and restart the printer.
4. Enter service mode by pressing specific buttons on the printer (Print, resume, and power buttons) in a sequence.
5. Use the Canon service tool to set the time and reset the printer.
6. Restart the printer, which should now function without displaying Error 6700.

It's essential to note that using the correct version of the Canon service tool is crucial for successful troubleshooting. In some cases, switching to an older version (e.g., v3400) might yield better results compared to newer versions.

Canon Service Tool, Service Mode, and "Time-agnostic Mode"

The Canon service tool is a valuable resource for resetting various printer settings, including the time setting affected by Error 6700. Entering service mode is necessary to utilize this tool effectively. However, it's important to distinguish between service mode and "time-agnostic mode," especially when dealing with Error 6700.

To enter service mode, follow the specified button sequence on the printer. It's worth noting that even when the printer displays Error 6700 in service mode, it might still be functional. This state, referred to as "time-agnostic mode," allows basic printer functions despite not knowing the current time.

Sending Print Commands via Button Presses

In situations where connecting a computer for troubleshooting isn't feasible, you can execute basic printer tasks using button presses. This feature is particularly useful for tasks like nozzle checks without the need for external devices.

By holding down the resume button and observing the number of flashes from the power lamp, you can trigger specific commands:

• Cleaning the print head
• Printing the nozzle check pattern
• Executing tasks such as paper handling and maintenance routines

Error B200 and Printhead

Another common error you might encounter is Error B200, indicating a problem with the printhead. Unlike Error 6700, which is often resolved by resetting the printer, B200 signifies a more severe issue that might require replacing the printhead.

Attempts to mitigate B200, such as cleaning printhead contacts or resetting printer settings, may not always yield successful results. If you consistently encounter Error B200 despite troubleshooting efforts, it's advisable to consider replacing the printhead for optimal printer functionality.

Understanding common errors like Error 6700 and Error B200, along with effective troubleshooting techniques, can help you maintain and restore the functionality of your Canon Pixma PRO-1 printer. By following the outlined steps and leveraging available resources like the Canon service tool, you can address issues efficiently and ensure a seamless printing experience.
