HP OfficeJet Pro 9015e Carriage Jam and Service Station Clicking: What to Check

Question:

On my HP OfficeJet Pro 9015e, I can turn the large gear on the left and move the waste/service station easily by hand. After I put the printhead back, the carriage moves right, then left and back right. At that point the station will not move into place. It clicks repeatedly, and the carriage snaps left near its stop. What should I check?

Thank you for contacting BCH Technologies, and I apologize for the delayed reply. Printer problems are urgent, and we want to give you a careful, detailed answer rather than point you toward a part without enough evidence. Thank you for supporting BCH and our YouTube channel.

The key clue is that the service station moves when you turn its gear manually but appears to skip or stall during the printer's startup sequence. That suggests a problem with the station's powered drive or timing. Dried ink or debris could bind the mechanism. A worn gear, coupling, or drive component could slip under load. A carriage alignment or printhead seating problem could also interfere. These are possibilities, not confirmed diagnoses, and the clicking alone cannot identify a failed part.

Turn the printer off, unplug it, and let the carriage stop before inspecting anything. With good light, look only at the accessible station path and large gear for loose scraps, hardened ink, damaged teeth, or a part sitting out of place. Check that the printhead is fully seated and the carriage path is clear. If a component does not move with gentle pressure, do not force it. Keep fingers, tools, and cleaning fluid away from exposed electrical contacts and ribbon cables.

Do not keep restarting the printer while the mechanism clicks or the carriage strikes its stop. Repeated attempts can damage gears or the carriage drive. Do not replace the printhead or mainboard based only on this symptom; a part that moves by hand may still bind or slip when driven, and a replacement will not fix the underlying cause if the timing or drive is wrong.

If the same sequence repeats after a safe visual check, a repair technician should inspect the service-station drive, gear engagement, carriage motion, and timing under the HP OfficeJet Pro 9015e's service procedure before parts are ordered. Board-level testing may be appropriate only if the mechanical drive and connections check out. You can also search the BCH Technologies YouTube channel [https://youtube.com/@bchtechnologies] for "9015e carriage jam" or "HP service station" to see the mechanism and safe access points. If you would rather have the printer evaluated, contact BCH Technologies about repair service and include the model, the startup sequence, and a short video of the clicking.
