If you've recently acquired a Canon MP730 multifunction printer and are facing power-up issues or experiencing a "Wrong Cartridge" message on the LCD display, you're not alone. In this tech overview, we'll delve into the conversation among users who encountered similar problems and explore potential solutions. Whether you're a seasoned printer enthusiast or a novice, read on to discover practical insights into resolving these issues.
Identifying the Issue: The "Wrong Cartridge" Message
Acquiring a Canon MP730 with a "Wrong Cartridge" error message displayed on the LCD can be frustrating. This error typically indicates a defective print head. To address this, they decided to power down the printer and allow it to park the printhead, a common troubleshooting step.
Attempted Resolution: Print Head Replacement
To address the "Wrong Cartridge" error, a user purchased a $5 iP3000 printer, which shares the same printhead as the MP730. However, they encountered a new problem—the MP730 would not power up. They suspected that the faulty print head might be preventing the printer from turning on. Moreover, they were unable to move the printhead to the center position.
Challenges with Canon MP730 Power Supply Access
The power supply of the MP730 is situated at the bottom, making it challenging to access compared to newer printer models. They had not yet checked the power supply, adding an additional layer of complexity to the troubleshooting process.
Similar Issues with MP780 Printers
Users shared their experience with MP780 printers, which are newer models than the MP730. They shared that, in their experience, if an MP780 failed to power up, even if it was due to a bad print head, replacing the power supply did not resolve the issue. This information suggests that the power supply might not be the root cause of power-up problems in these Canon printers.
Safe Print Head Removal Procedure
A suggested procedure for safely removing a defective print head from a printer involves turning on the printer and, as soon as the print head starts to move from its park position, pulling the power cord to prevent it from returning to the park position. This technique could potentially prevent further damage or complications during print head removal.
Understanding the "Wrong Cartridge" Error
Emphasizing that the primary issue in this discussion is the printer's failure to power up, and the exact cause remains unknown, it's agreed that if the error message remains "Wrong Cartridge," there is little risk in transferring working print heads between printers. However, when a printer refuses to power up for an unspecified reason, caution is warranted.
Exploring the Impact of Print Head Removal
An intriguing discovery from the discussion is the possibility of a printer powering up after removing the print head. Inquiries were made regarding whether the printer displayed an error message about the cartridge or print head and whether it stayed powered up without the print head. This raises questions about whether a new print head might revive the printer.
