Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — entry home INKJET all-in-one: An entry inkjet AIO for occasional home printing. Inkjet printheads CLOG if unused, and light users are the most affected — faded/streaked output is usually a clog; run clean-printhead/nozzle-check. Print at least occasionally to prevent it.
HP+ / '+e' — genuine ink + internet: HP+: genuine HP ink, internet and enrolment; Instant Ink cartridges stop if the plan lapses; third-party ink rejected.
Connectivity: Wi-Fi/USB via HP Smart; 'offline' is usually Wi-Fi drop or wrong queue.

Questions that only have an answer for the HP DeskJet 4155e

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

My HP DeskJet 4155e sat unused and now prints badly.+

That is the most common inkjet problem — when an inkjet sits idle, the ink in the printhead dries and clogs the tiny nozzles, giving faded, streaked or blank output. Run the clean-printhead/nozzle-check cycle from the HP Smart app two or three times and print a test page each time. Severe clogs may need several cleans (which use ink) or a soak. To avoid it, print something at least every week or two. Entry inkjets are especially prone because light users leave them idle.
