Question 1

getting an 'out of memory' error on the screen when trying to print a big pdf or a photo-heavy document.

Accepted Answer

DIAGNOSIS The printer itself has limited RAM to process complex print jobs before sending them to the physical print engine. A large, high-resolution PDF or a document with lots of images can exceed that buffer. FIX Don't hit 'OK' to clear the error on the printer—that will cancel the job. Go back to your computer. In your print dialog box, look for 'Properties' or 'Printer Properties'. Find the 'Paper/Quality' tab. Change the 'Print Quality' from 'Best' or 'Maximum DPI' down to 'Normal' or 'Draft'. This reduces the amount of data the printer has to process. Also, make sure you're printing the 'Actual Size' and not 'Fit to Page', which can add processing overhead. IF THAT DIDN'T WORK Break the job up. If it's a PDF, try printing a subset of pages (like 1-5, then 6-10) instead of the whole document at once. Alternatively, on your computer, use software to reduce the PDF's resolution or compress the images before sending it to print. HEADS UP This error is about the printer's processing memory, not its storage or your computer's memory. Upgrading your computer's RAM won't help. This is a hardware limitation of the printer, so reducing the complexity of the job is the only real fix.

Question 2

printer goes to sleep and then won't wake up for a network print job, i have to turn it off and on again every time.

Accepted Answer

DIAGNOSIS This is usually a power management setting conflicting with your network's router. The printer's 'Deep Sleep' or 'Auto-Off' mode is too aggressive and severs its network connection to save power. FIX On the printer's touchscreen, tap Settings (the gear icon). Go to 'Preferences' > 'Sleep Mode' or 'Auto-Off'. Change this setting to 'Never' or to the maximum time available. Also, check for a separate 'Deep Sleep' setting in the same menu and disable it. This will keep the printer's network chip active and ready to receive jobs. IF THAT DIDN'T WORK The issue might be with your router's configuration, not the printer. Some routers aggressively drop connections from devices they deem 'idle'. Try assigning a static IP address to your printer in your router's settings, as this can sometimes prevent it from being culled from the network list. HEADS UP Turning off sleep mode will use more power—the printer will stay in a 'ready' state. It's a trade-off between convenience and energy use. If you print infrequently, you might just have to accept walking over to tap the screen to wake it before sending a job.

Question 3

scanner glass gets dirty constantly and leaves streaks on every scan or copy, how do i clean it properly without damaging it?

Accepted Answer

DIAGNOSIS The streaks are from dust, fingerprints, or dried smudges on either the flat glass you place the document on or, more commonly, the underside of the scanner lid (which often has a white backing sheet that gets dirty). FIX Power off the printer. Lift the scanner lid. Use a can of compressed air to gently blow any loose dust off the glass and the white backing on the lid. For fingerprints or smudges, put a small amount of distilled water or isopropyl alcohol (90% or higher) on a microfiber cloth—never spray directly onto the glass. Wipe the glass in one direction, not circles. Use a dry part of the cloth to immediately buff it dry. For the white backing on the lid, wipe gently with a dry cloth first; if needed, use a barely damp cloth and be careful not to saturate it. IF THAT DIDN'T WORK If streaks are still appearing in the same place on every scan, there might be a tiny scratch on the glass or a permanent stain on the backing sheet. You can test which it is by scanning with the lid open and a blank sheet of white paper placed over your document. If the streak disappears, the issue is the lid's backing sheet. HEADS UP Never use window cleaner, acetone, or other abrasive chemicals. They can strip anti-reflective coatings. Also, avoid paper towels or tissues—they can scratch the glass. The glass is more fragile than it looks, so don't press hard.

Question 4

it makes a loud grinding or crunching noise when it starts up or when printing, sounds like it's coming from the right side.

Accepted Answer

DIAGNOSIS That's almost certainly the carriage assembly (the part that holds the ink cartridges) hitting an obstruction or struggling to move on its rail. The cause is usually dried ink gunk on the silver rod (the rail) it slides on, or a foreign object like a paperclip or torn piece of paper in its path. FIX Unplug the printer. Open the cartridge access door. You'll see the carriage on the right and a long, shiny metal rod it rides on. Move the carriage by hand from side to side—it should glide smoothly. If it's sticky or crunchy, you've found it. Put a couple drops of distilled water on a lint-free cloth and thoroughly wipe the entire length of that silver rod. Then use a dry part of the cloth to wipe it again. Manually move the carriage back and forth a few times to spread the lubrication. IF THAT DIDN'T WORK While you have the door open, check the white plastic strip that runs along the back of the carriage path. This is the encoder strip. If it's smudged with ink or dust, the carriage can lose its position. Gently wipe it clean with a dry cloth. Never use alcohol or cleaner on it. HEADS UP Never use oil, WD-40, or household cleaners on the metal rod. They'll attract more dust and gum things up worse. A tiny bit of moisture from water is all you need to dissolve ink residue. If the noise persists after cleaning, a mechanical part in the carriage motor might be failing.

Question 5

my prints are coming out with streaks or faded lines, especially in colors, even after running the cleaning utility a bunch of times.

Accepted Answer

DIAGNOSIS Repeated software cleanings can actually waste ink without fixing a physical clog. The issue is likely a clogged printhead nozzle, or the cartridges themselves are low (even if the software says they're not). FIX On the printer's touchscreen, go to Settings (the gear icon) > Printer Maintenance > Clean Printheads. Run this utility once. Then, print a 'Diagnostic Report' from the same menu. Look at the color patterns on the report. If you see gaps or missing lines in the color blocks, the clog remains. The most effective fix is often manual: place a damp, folded paper towel in the tray at the bottom of the carriage (where the cartridges park), close the door, and let the printer sit powered ON overnight. The gentle humidity can loosen dried ink. IF THAT DIDN'T WORK If one color is consistently terrible, the cartridge might be faulty or empty. Even if it's not giving a low-ink warning, try replacing that specific color cartridge. Genuine HP cartridges have the printhead built-in, so a new cartridge is a new printhead for that color. HEADS UP Don't run the cleaning utility more than twice in a row. It's incredibly wasteful on ink. If you're not printing regularly, the printer will run automatic maintenance cycles that use ink anyway, which is why clogs can happen. Printing a color photo or graphic once a week can help keep things flowing.

Question 6

the printer screen says 'cartridge problem' or 'cartridge error' for a brand new genuine hp ink cartridge i just put in.

Accepted Answer

DIAGNOSIS The printer isn't reading the chip on the new cartridge properly. This can happen if there's a bit of plastic from the packaging still on the contacts, the contacts on the cartridge or inside the printer are dirty, or the cartridge wasn't seated fully. FIX Power the printer on and open the cartridge access door. The carriage will move to the center. Press down firmly on the cartridge that's showing the error until you feel a definite click. Don't just tap it. If that doesn't clear it, remove the cartridge. Look at the copper-colored contacts on the back. Use a dry, lint-free cloth (like a microfiber glasses cloth) to gently wipe them. Do the same for the shiny contacts inside the printer where the cartridge sits. Reinstall the cartridge firmly. IF THAT DIDN'T WORK Try the other cartridge slot. Swap the 'problem' cartridge with the one from the other slot. If the error moves with the cartridge, the cartridge itself might be defective. If the error stays in the same slot, there could be a deeper issue with the printer's carriage. HEADS UP Never use anything wet or abrasive (like a paper towel) to clean the contacts. Static from a dry cloth is fine. Also, make sure you removed the entire plastic tape from the printhead nozzles on the bottom of the cartridge before installing it.

Question 7

just got a 9015e and it won't connect to my wifi during setup, the screen just keeps searching forever.

Accepted Answer

DIAGNOSIS The printer's initial Wi-Fi setup can be fussy, especially with modern dual-band routers that use the same name for 2.4GHz and 5GHz networks. The 9015e needs a 2.4GHz connection. FIX Skip the wireless setup on the printer's touchscreen for now. On your computer that's connected to your Wi-Fi, download and run the full 'HP Smart' app from hp.com. When it prompts you to set up a new printer, connect the printer to your computer directly using a USB cable. The app will guide you through the rest and push the correct Wi-Fi settings to the printer over the USB connection. IF THAT DIDN'T WORK Your router might be blocking the connection. Temporarily disable any advanced features like 'AP Isolation' or 'Client Isolation' in your router's settings. Also, try moving the printer closer to the router during setup, as physical obstructions can cause the initial handshake to fail. HEADS UP Don't waste time typing a complicated Wi-Fi password on the tiny touchscreen. The USB method via the HP Smart app is almost always faster and more reliable for getting this model online the first time.

Question 8

my hp officejet pro 9015e keeps saying 'paper jam' but there's no paper stuck anywhere, i've checked everything.

Accepted Answer

DIAGNOSIS Yeah, this one's a classic. The printer's internal sensors are detecting something—often a tiny piece of torn paper, or a sensor flag itself is stuck—even if the main paper path looks clear. FIX First, power the printer completely off and unplug it from the wall for a minute. Open all the doors: the front cartridge access door, the rear output tray, and the duplex unit (the flap on the back). Shine a flashlight inside and look for any shred of paper, especially around the rollers in the duplex unit and deep in the rear output area. Use tweezers to gently pull out any debris. Also, manually wiggle all the little plastic sensor flags you can see to make sure they're moving freely. IF THAT DIDN'T WORK The issue might be with the paper tray itself. Remove the tray completely. Look at the metal paper length guide at the back of the tray cavity inside the printer. Sometimes it gets bent or has a sticker stuck to it, which tricks the sensor. Gently straighten it if it's bent. HEADS UP Be really careful not to force any doors or levers when the printer is off. If you break a plastic sensor flag, you're looking at a service call. Also, using paper that's too light or has a rough edge can cause micro-tears that trigger this.
