HP printer error 0x6100004a: the carriage is still obstructed

What it means, and when it appears

HP describes 0x6100004a as a Printer Failure message on the control panel, and adds the detail that makes it diagnosable: this error can occur after a paper jam message. That is the context to hold on to. The printer is not reporting a new fault so much as refusing to accept that the last one is over.

So the first question is not what 0x6100004a means in the abstract but what happened just before it. A jam that was cleared quickly, in the dark, behind a printer on a shelf, is exactly the situation that leaves something behind.

HP's own first instruction is a reminder rather than a step: make sure the cartridge access door is fully closed, to avoid errors or other problems. A door that looks shut and is not seated produces its own set of failures.

Clearing what is left behind

HP's sequence starts with the paper path. Open the cartridge access door, remove the paper path cover, and remove any torn paper, labels or other obstruction that might be inside.

Labels are named specifically and are worth taking seriously. A label sheet that has separated inside the printer leaves adhesive-backed fragments stuck to rollers and guides, and those are both harder to see and harder to remove than plain paper.

Reinserting the cover correctly matters as much as removing the obstruction. HP asks you to make sure it is fully inserted into the printer so that it does not interfere with closing the access door, and then to close the door ensuring it is fully seated. A cover left proud holds the door open by a millimetre and reproduces the fault.

The power sequence, which is not intuitive

If the error survives the physical clear, HP gives a specific sequence to clear the message, and the order is deliberate enough that improvising will not work. Press the power button to turn the printer off. With the printer off, open the cartridge access door. Turn the power on and wait for the carriage to move.

Then, with the printer on, unplug it from power. Remove the ink cartridges and set them aside — HP notes it might be necessary to manually slide the carriage to reach them. With the access door still open, turn the printer on and wait for it to complete its start-up sequence.

Once the carriage returns to the centre and the error is clear, install the ink cartridges. HP adds a detail worth knowing before you give up: if the error does not clear, repeat these steps up to three times.

That instruction to repeat is unusual and it is genuinely part of the procedure rather than a hedge. People perform the sequence once, see the error again, and conclude the printer is broken — when HP's own guidance expects it may take more than one attempt.

When it is service

HP's endpoint is short: service or replace the product if the issue persists after completing all the preceding steps, and go to HP Customer Support to schedule a repair or replacement. In Asia Pacific, HP notes you will be directed to a local service centre.

Check the warranty before booking anything. HP points at its Product Warranty Check and notes that repair fees might apply for out-of-warranty products — which, on an inexpensive all-in-one, frequently changes the decision from repair to replace.

Before that call, be able to say how many times the power sequence was attempted, since HP's own instruction is up to three. That is the first thing that separates a genuine fault from a procedure that was tried once.

Sources and review notes

Checked on September 8, 2026. Based on HP's support document for the 0x6100004a error on OfficeJet All-in-One printers. The clearing steps, the power sequence and the instruction to repeat up to three times are HP's. The note about label fragments and the framing of the error as a jam that was never fully cleared are editorial. HP's support pages render only in a browser and are not reliably fetchable.
