Canon has published a product advisory for a potential power issue affecting selected imageCLASS MF272dw, MF273dw and LBP122dw laser printers. The issue may cause an affected unit to shut down unexpectedly while printing and, in some cases, prevent it from restarting through the normal power-button cycle. The advisory is important for owners who rely on these compact printers for home-office or small-business documents.
What the reported problem looks like
The symptom described by Canon is a sudden shutdown during a print job. A user may press the power button to turn the printer back on, but the normal off-and-on procedure may not restore operation. Because a power interruption can resemble several other printer faults, users should avoid assuming that the problem is caused by a driver, wireless connection or empty toner cartridge.
A device that loses power while printing can interrupt a document, leave a job in the computer’s queue or create uncertainty about whether the page was completed. In a small office, repeated interruptions can affect invoices, shipping labels, customer paperwork and other time-sensitive work. The advisory therefore deserves attention even if the printer has only experienced the issue once.
Canon’s temporary recovery guidance
Canon describes a temporary workaround for a unit that shuts down and will not restart through ordinary power cycling. The procedure is to disconnect the power cord directly from the wall outlet or power source, wait for ten minutes, reconnect the cord and then attempt to power the printer on again. The waiting period is intended to allow residual charge and the device’s error state to clear.
This procedure should be followed carefully. Users should disconnect the printer from the wall rather than relying only on the printer’s power button, and they should avoid opening the device or attempting electrical repairs. If the printer is connected through a power strip or uninterruptible power supply, the user should follow the manufacturer’s safety guidance for that equipment as well.
Why the workaround is not a permanent repair
Canon states that the temporary recovery step may restore operation, but the problem can recur until a permanent repair is completed. That distinction is critical. A printer that powers on after the ten-minute wait should not automatically be considered fixed. Owners should consult the applicable Canon support channel and check the advisory for the latest service instructions and eligibility details.
Users should have the exact model name and serial number available when contacting support. They should also note when the shutdown occurred, whether the printer was actively printing, what error indicators appeared and whether the temporary recovery method worked. These details can help support staff identify the correct next step.
Practical steps while waiting for service
For essential work, businesses may want to arrange a backup printer or an alternative document process rather than depending on a unit that has already shown the symptom. Avoid repeatedly forcing the printer to restart, and do not use unofficial repair instructions or attempt to bypass internal protection systems. Keep the printer in a well-ventilated location and use a stable, correctly rated power outlet.
What owners should take away
The advisory does not mean every unit in the listed families will experience a failure. It does mean owners of the named models should recognize the symptom and know where to find official assistance. The ten-minute unplug procedure is a temporary recovery measure, not a substitute for a permanent service remedy. Checking the model, recording the symptoms and contacting Canon support are the most sensible next steps.
Keep a record for the service team
If the shutdown occurs, write down the exact model, serial number, approximate page count and what the printer was doing immediately before it stopped. Note whether the display went dark, whether any indicator remained lit and whether the temporary recovery method restored operation. These details can help support staff distinguish the reported power condition from a separate electrical or mechanical fault.
Do not open the printer casing or attempt to repair internal power components. Laser printers contain electrical parts that should only be serviced by qualified personnel. If the printer is used for essential business documents, arrange a temporary alternative and keep affected print jobs in a safe queue until the device has been checked. The goal is to restore service without creating a second safety or data-handling problem.
