Question 1

instant ink says my cartridge levels are wrong, like it says empty but it's new. now it won't let me print.

Accepted Answer

DIAGNOSIS The printer's ink level monitoring, which is tied to the HP+ and Instant Ink system, has lost communication with HP's servers or has a corrupted local counter. FIX First, check your internet connection—the printer needs to phone home to validate Instant Ink cartridge status. If online, restart the printer. If that doesn't sync, you need to reset the ink counters. Turn the printer on. Open the cartridge access door. Press and hold the (i) information button for about 5 seconds until the carriage moves. The printer will reset its ink level estimation. IF THAT DIDN'T WORK You may need to re-register the cartridges. In the HP Smart app, go to your printer, then 'Instant Ink', and look for an option like 'Manage Plan' or 'Update Cartridge Information'. There's often a 'Sync' or 'Refresh' button. Follow the prompts. HEADS UP This is a downside of the HP+ system on this model. If you use non-HP or refilled cartridges, the printer will likely lock you out from printing entirely. The 2855e with HP+ is designed to only work with HP-original chips that can communicate with the service.

Question 2

how do i cancel a print job stuck in the queue on this thing? it just says 'processing' forever.

Accepted Answer

DIAGNOSIS The printer's internal memory has hung on a corrupted print job, or your computer's spooler is stuck. The 'processing' state means it's received data but can't interpret or execute it. FIX The fastest fix is to restart the printer's network connection. On the printer, press and hold the Wireless button for about 3 seconds until the light blinks. This disconnects it from the network and kills any pending wireless jobs. Wait 10 seconds, then press the Wireless button again to reconnect. Alternatively, just power the printer off and on. The stuck job should clear. IF THAT DIDN'T WORK You have to clear the queue from the source. On a Windows PC, go to Settings > Devices > Printers & scanners, select your HP 2855e, click 'Open queue', and cancel all documents. On a Mac, go to System Settings > Printers & Scanners, right-click the printer, and 'Reset Printing System'. HEADS UP Printing very large PDFs or high-res photos can cause this, as the printer's memory buffers overflow. For big files, try printing in smaller chunks. Also, switching from 'WiFi Direct' to your main home network in the HP Smart app can prevent these hangs.

Question 3

printed pages have streaks or lines of missing color, especially after not using it for a week or two.

Accepted Answer

DIAGNOSIS The inkjet printhead nozzles are clogged with dried ink. This is the universal plague of inkjet printers, and it hits this model hard because the printhead is built into the cartridges, which can dry out. FIX Run the printer's built-in printhead cleaning utility. On the printer itself, press the (i) information button to get to the settings menu, navigate to 'Tools', then 'Printer Maintenance', and select 'Clean Printhead'. You can also do this from the HP Smart app under Printer Settings. This will waste a bit of ink. After it runs, print the 'Print Quality Report' from the same menu to check. IF THAT DIDN'T WORK If software cleaning fails, you need to clean the cartridge contacts and the contacts inside the printer. Power off, remove the cartridges, and use a dry cotton swab to gently wipe the copper-colored contacts on both the cartridges and inside the carriage. Reinstall and try another cleaning cycle. HEADS UP Don't run the cleaning cycle more than twice in a row—it's a huge ink-waster and can flood the waste pad. If two cycles don't fix it, the cartridge/printhead is likely too dried out and needs replacement. Using the printer at least once a week helps prevent this.

Question 4

scanner on my deskjet 2855e won't work, hp smart app just says 'scanner not detected' or freezes.

Accepted Answer

DIAGNOSIS The scanner flatbed cable or the scanner assembly itself has a loose connection or has failed. This is a known weak point in this all-in-one design. FIX First, this is almost always a software/driver issue. Uninstall the HP Smart app and any other HP printer software from your computer or phone. Reboot your device. Download and install the full HP DeskJet 2855e driver package from the official HP support website, not just the app. This package includes the proper scanner drivers. During installation, connect via USB cable if possible to ensure detection. IF THAT DIDN'T WORK If the scanner glass doesn't light up at all when you power on the printer, there's a hardware fault. Perform a full reset: turn off, unplug, wait 60 seconds, plug back in. If the light still doesn't come on, the internal cable connecting the scanner to the mainboard is likely disconnected. HEADS UP The scanner often won't initialize if there's a paper jam error or cartridge error active. Clear any other error messages on the printer first. Also, the scanner only works when connected via WiFi or USB—not over Bluetooth.

Question 5

my hp 2855e is making a loud grinding or crunching noise when it tries to print, like gears stripping.

Accepted Answer

DIAGNOSIS That's the sound of the printhead carriage hitting an obstruction or moving on a dry track. Most often, it's a stuck piece of paper, a forgotten packing material, or the carriage guide rail has no lubrication. FIX Immediately cancel any print job and turn the printer off. Open the front cartridge access door. The printhead carriage should be in the center. Manually inspect the path for any scraps of paper, the little orange plastic tape from new cartridges, or other debris. Gently move the carriage by hand from side to side—if it's stiff, you've found the issue. Power the printer back on; it will often home itself and the noise may stop if the obstruction was cleared. IF THAT DIDN'T WORK If the carriage moves freely but still grinds when powered, the encoder strip (the clear plastic strip behind the carriage) is likely dirty. With the printer off, use a dry cotton swab to very gently wipe it clean. Do not use liquids, as they can ruin the strip. HEADS UP Never force the carriage if it's electronically locked. If it won't budge with gentle pressure, turn the printer on first, let it try to initialize, then turn it off again—the lock might release. Forcing it can break the plastic gear train inside.

Question 6

printer says 'out of paper' when there's definitely paper loaded in the tray. it just won't pick it up.

Accepted Answer

DIAGNOSIS The paper pickup roller inside the printer is either dirty, dusty, or has worn smooth, so it can't grip the top sheet in the tray. This happens a lot with this model if you use it infrequently. FIX Turn the printer off and unplug it. Open the rear access door (the one where paper comes out). Look inside and to the left—you'll see a gray rubber roller. Dampen a lint-free cloth with a little distilled water (not isopropyl alcohol on the rubber). Manually rotate the roller with your finger, wiping the entire circumference clean. Let it dry for a minute, close up, plug in, and try with a fresh stack of plain paper, making sure the guides are snug. IF THAT DIDN'T WORK The paper sensor, a little plastic flag inside the tray area, might be stuck. With the printer off, remove all paper. Use a flashlight to look in the empty tray slot. Gently wiggle any small plastic lever you see with a pencil eraser to free it up. HEADS UP Overfilling the tray beyond the 100-sheet mark puts pressure on the mechanism and makes this failure happen faster. Also, glossy or heavy paper is harder for this entry-level roller to grab consistently.

Question 7

set up my 2855e but it won't connect to wifi, keeps saying connection failed. my phone and laptop are fine.

Accepted Answer

DIAGNOSIS Yeah, this one's common. The printer's wireless setup is finicky, especially with dual-band routers (2.4GHz and 5GHz). The DeskJet 2855e only connects to the 2.4GHz band. FIX First, make sure you're connecting to the 2.4GHz network. Its name might be something like "YourNetwork_2G". During setup with the HP Smart app, when it asks for the password, there's a hidden step. If it fails, go back and on the network selection screen, tap the three dots or 'Advanced' and choose "Set up a new network". Re-enter the 2.4GHz name and password there—this often bypasses a glitch in the direct selection method. IF THAT DIDN'T WORK The printer's wireless module might need a reset. Turn the printer on, then press and hold the Wireless and Cancel buttons together for about 5 seconds until the lights blink. This resets the network settings. You'll have to start the setup process in the HP Smart app from scratch. HEADS UP If your router broadcasts a single name for both bands (band steering), the printer will often fail. You'll need to log into your router and temporarily disable the 5GHz band or split the networks into two separate names just for the setup.

Question 8

my hp deskjet 2855e just flashes the power light and won't actually turn on, no display or anything.

Accepted Answer

DIAGNOSIS The printer is stuck in a failed boot cycle, usually triggered by a corrupted firmware update or a temporary power surge. The flashing light means it's trying and failing to initialize. FIX Unplug the power cord from the back of the printer AND from the wall outlet. Wait a full 60 seconds—this lets the internal capacitors drain completely. While it's unplugged, press and hold the power button on the printer for about 10 seconds (this discharges any residual static). Plug everything back in firmly and press the power button once. It should go through a normal boot sequence. IF THAT DIDN'T WORK The issue might be with the power supply itself. Try a different power outlet that you know works, and make sure you're using the original HP power cord that came in the box. A different cord might not deliver the right voltage. HEADS UP If it still just flashes after this, the main logic board might be fried. HP's warranty process for this usually starts with them having you run the same power cycle steps, so you've already done their first-line troubleshooting.
