You loaded a fresh cartridge into your HP DeskJet 4255e, expected a clean print, and instead the printer flashed a not-recognized or incompatible error. It is a frustrating spot, because the cartridge often looks perfectly fine sitting in its slot. The good news is that most cartridge-recognition errors on this little all-in-one come from temporary glitches, dirty contacts, or a cartridge the printer simply will not accept, and you can usually clear them yourself in a few minutes.
Work through the fixes below in order. They are arranged from the quickest and safest to the more involved official resets, so you avoid touching the hardware until you have ruled out the simple causes first.
Start With a Full Power Reset
A surprising number of cartridge-not-recognized states are just temporary electronic hiccups, and a proper power cycle clears them before you ever open the printer. This is different from simply pressing the power button, because it drains residual power and forces the printer to re-read the cartridges from scratch.
- 1.With the printer turned on, disconnect the power cord from the printer.
- 2.Unplug it from the power source.
- 3.Wait 60 seconds.
- 4.Reconnect the power cord directly to a wall outlet and to the printer.
- 5.Turn it on.
Reconnecting directly to a wall outlet rather than a surge strip or extension cord is part of the official steps and helps rule out a weak power connection. If the message clears after this, you are done. If not, move on to checking the cartridges themselves.
Reseat the Black and Tri-Color Cartridges
A cartridge that is not fully snapped into place will read as missing or not recognized, even if it looks installed. The DeskJet 4255e uses one HP 67 or 67XL Black and one HP 67 or 67XL Tri-Color cartridge, each in its own color-coded slot, so it is worth confirming both are firmly seated.
- 1.Open the cartridge access door.
- 2.Make sure both the Black and Tri-Color cartridges are firmly seated.
- 3.If one is sticking out farther than the other, press it in until it snaps into its color-coded slot.
- 4.Close the door.
Listen for the snap, since that click is your confirmation the cartridge has seated fully home. Then let the printer recheck the cartridges before deciding whether the error is gone.
Remove Any Leftover Protective Tape
New cartridges ship with protective tape over the contacts, and a stray piece left behind will block the printer from reading the cartridge entirely. This is one of the most common causes on a brand-new install.
- 1.Take out the cartridge.
- 2.Hold it by the plastic sides only, and do not touch the copper-colored contacts or the ink nozzles.
- 3.Remove any protective tape that might be on the contacts.
- 4.On a brand-new cartridge, pull the orange pull-tab and plastic wrap completely off before reinstalling.
Touching the contacts or nozzles with your fingers can cause its own recognition and print-quality problems, so handle the cartridge only by the plastic. Once the tape is fully removed, reinstall the cartridge and press until it snaps into place.
Clean the Cartridge and Carriage Contacts
If the cartridge is genuine and properly seated but still not recognized, dirty or smudged electrical contacts are a likely culprit. Cleaning them gently with the right cloth and liquid often restores the connection.
- 1.Lightly dampen a lint-free cloth with distilled water.
- 2.Gently wipe the copper-colored contacts on the cartridge.
- 3.Wipe the electrical contacts inside the carriage.
- 4.Wait 10 minutes for the contacts to dry.
- 5.Reinsert the cartridge.
Use distilled water specifically, and never touch the ink nozzles or the copper-colored contacts with your fingers while you work. Giving the contacts the full 10 minutes to dry before reinserting helps prevent a short that could keep the error going.
Confirm You Are Using Original HP Cartridges
The DeskJet 4255e is an HP+ enabled printer, and that detail is one of the biggest reasons a cartridge reads as not recognized or incompatible. If HP+ was activated during setup, the printer requires exclusive use of Original HP Ink cartridges for the life of the printer.
That means a used, refilled, counterfeit, or non-HP cartridge can show as not recognized or incompatible even when nothing is physically wrong with it. If you have been using a third-party or refilled cartridge, this is a very likely cause.
The fix is to replace it with a genuine HP 67 or 67XL Black or Tri-Color cartridge. On an HP+ printer this is not optional, since it is a condition of the printer working at all, so swapping to an Original HP cartridge is the only path forward if HP+ was enabled.
If This Is First-Time Setup, Install the SETUP Cartridges
A brand-new DeskJet 4255e must be initialized with the SETUP cartridges that came in the box, not with standard replacement cartridges. If you see a Use SETUP Cartridges message, the printer has not completed its initial setup yet.
Look for the word SETUP printed on the cartridge label, since these are the ones that shipped inside the printer box. If you cannot find them, check the original packaging the printer came in.
- 1.Install the SETUP cartridges that came in the printer box.
- 2.Seat each one into its color-coded slot.
- 3.Press until it snaps in.
Once the printer has initialized with the SETUP cartridges, you can switch to standard HP 67 or 67XL cartridges later. Skipping this step on a new printer is a frequent reason setup stalls with a recognition error.
Update the Printer Firmware
Outdated firmware can cause a printer to misread otherwise-good cartridges, and an update sometimes resolves stubborn recognition errors. You handle this through the HP app (formerly HP Smart) on your computer or mobile device.
- 1.Open the HP app and click your printer.
- 2.Click Advanced Settings, or go to Printer Settings, click View All, then Advanced Settings.
- 3.Under Firmware Update, click Check for Update.
- 4.Click Update if one is available.
Do not turn off the printer during a firmware update, as interrupting it can leave the printer in a worse state than the original error. Let the update finish completely, then check whether the cartridge is now recognized.
Restore Factory Defaults, Then Reach Out to HP
If the cartridge still is not recognized after everything above, restoring factory defaults gives the printer a clean slate. This is the official reset for most HP DeskJet and ENVY models, including this one. Be aware that restoring factory defaults clears the printer's settings, including its saved Wi-Fi network, so you will need to set the printer up on your network again afterward.
- 1.Open the cartridge access door.
- 2.On the control panel, press and hold the Power and Wireless buttons for at least 3 seconds.
- 3.After about 20 seconds, close the cartridge access door.
If you only want to reset the network and Wi-Fi rather than restore full defaults, press and hold the Wireless and Cancel buttons for 5 seconds until the Wireless light blinks. That network reset puts the printer back into Wi-Fi setup mode without affecting the rest of its configuration.
If the recognition error persists even after a factory-defaults reset, the problem may need direct help. At that point, contact HP Customer Support for further options.
Frequently Asked Questions
Which cartridges does the HP DeskJet 4255e use?
It uses HP 67 or HP 67XL Black and HP 67 or HP 67XL Tri-Color Original Ink Cartridges, and it ships with HP 67 SETUP cartridges in the box. It is a cartridge-based inkjet, not a refillable ink-tank printer.
Why does my third-party cartridge show as incompatible?
The DeskJet 4255e is HP+ enabled. If HP+ was activated at setup, the printer requires exclusive use of Original HP Ink cartridges for the life of the printer, so a used, refilled, counterfeit, or non-HP cartridge can read as not recognized or incompatible. Replacing it with a genuine HP 67 or 67XL cartridge resolves this.
What are SETUP cartridges for?
SETUP cartridges are the ones that come inside the printer box and are used to initialize a new printer. If a Use SETUP Cartridges message appears, install the cartridges that shipped with the printer to complete the initial setup.
Is restoring factory defaults the same as resetting Wi-Fi?
No. Restoring factory defaults uses the Power and Wireless buttons with the cartridge access door open and clears the printer's configuration, including its saved network. Resetting only the network uses the Wireless and Cancel buttons held for 5 seconds, which puts the printer back into Wi-Fi setup mode without a full reset.
Should I clean cartridge contacts with tap water?
No. Lightly dampen a lint-free cloth with distilled water only, then gently wipe the copper-colored contacts on the cartridge and the electrical contacts in the carriage. Wait 10 minutes for the contacts to dry before reinserting, and never touch the nozzles or copper contacts with your fingers.
