Question 1

why does my 4155e take forever to print, like several minutes just to spit out one page?

Accepted Answer

DIAGNOSIS This is usually a data transfer issue, not a mechanical one. The printer is waiting for the full print job to arrive over a slow or busy Wi-Fi connection, or your computer is sending it in a complex format. FIX First, check your connection. 1) Print a network configuration page from the printer's control panel (Settings > Reports > Network Configuration). It should show a strong signal. If the signal is weak, consider moving the printer or router. 2) Try printing a simple text document from your computer. If that's fast, the slowness is coming from complex graphics or a "print as image" setting in your software. 3) For a quick test, connect your computer directly to the printer with a USB cable. If it prints instantly, you've confirmed the Wi-Fi is the bottleneck. IF THAT DIDN'T WORK The printer might be set to a high-quality mode like "Best" or "Photo." Change the print quality to "Normal" or "Draft" in your print dialog box. This uses less data and prints much faster. HEADS UP If you're printing over a VPN or a corporate network, that can add massive delays. Try disconnecting from the VPN or printing from a personal device on your home network to see if that's the culprit.

Question 2

trying to scan from my phone with the hp smart app and it just won't find my 4155e printer.

Accepted Answer

DIAGNOSIS The printer and your phone need to be on the same Wi-Fi network. If one is on the 2.4GHz band and the other on 5GHz, or if you have a "guest" network, they can't talk. FIX 1) Check your printer's network: press the Wireless button on the control panel. It should show your network name. 2) On your phone, go to Wi-Fi settings and make sure you're connected to the exact same network (not a similarly named one). 3) Close the HP Smart app completely and reopen it. 4) In the app, tap the "+" to add a printer. It should search and find it. If it doesn't, the app might need to connect directly: hold the Wi-Fi button on the printer for 3 seconds until the light blinks, then try the app's "direct connection" option. IF THAT DIDN'T WORK Your router's firewall or settings might be blocking the discovery protocol. Try temporarily disabling your mobile data so your phone is forced to use only Wi-Fi, then try again. HEADS UP Many phones have a "private Wi-Fi address" setting (like on iPhones) that can interfere. For testing, you can turn that off for your home network in your phone's Wi-Fi settings, then turn it back on later for security.

Question 3

my prints are coming out with streaks and faded colors, i just put in new hp 67 ink, is the printer broken?

Accepted Answer

DIAGNOSIS This is almost never a broken printer. It's almost always clogged printhead nozzles. The ink dries out in the tiny holes if the printer isn't used regularly. FIX Run the printer's built-in cleaning utility. 1) From the control panel, swipe or press to find "Settings" (the gear icon). 2) Go to "Printer Maintenance" or "Tools." 3) Select "Clean Printheads" or "Print Quality." The printer will cycle ink through the nozzles to clear them. This uses a little ink. 4) Print the "Print Quality Report" from the same menu to check if it worked. IF THAT DIDN'T WORK If the cleaning cycle doesn't fix it, you might have a defective cartridge. Even new ones can be faulty. Re-seat the cartridges by opening the door, pressing them down to release, lifting them out, and firmly clicking them back in place. HEADS UP Don't run the cleaning cycle more than twice in a row. If two cycles don't fix it, let the printer sit for 12 hours. Sometimes the ink needs time to rehydrate dried clogs. Running it too much just wastes ink.

Question 4

the touchscreen on my deskjet 4155e is totally unresponsive, i can't press any buttons.

Accepted Answer

DIAGNOSIS The control panel has likely "frozen," which happens occasionally after a failed update or a minor software glitch. It's not broken, just stuck. FIX You need to do a full power cycle. 1) Turn the printer OFF using the physical button on the back. 2) Unplug the power cord from the wall outlet. 3) Wait 60 seconds—this lets all the internal capacitors drain. 4) Plug the power cord back in. 5) Turn the printer ON with the back button. Wait for it to fully start up; the screen should come back to life and be responsive. IF THAT DIDN'T WORK If the screen is still dead after the power cycle, there's a slim chance it's a hardware fault. Try the power cycle one more time, making sure you unplug from the wall, not just turn it off. HEADS UP Avoid using the front-panel power button (if yours has one) for this reset. Always use the main rocker switch on the back for a complete shutdown.

Question 5

my hp 4155e is making a horrible grinding noise when it tries to print, like a crunching sound.

Accepted Answer

DIAGNOSIS That crunching sound is almost always paper feeding incorrectly. It's trying to pull in more than one sheet at once, or a sheet is crooked and getting chewed up in the rollers. FIX 1) Turn the printer OFF immediately to prevent more damage. 2) Open the rear access cover (the flap on the back). You'll likely see the crumpled paper. 3) Firmly but gently pull the paper straight OUT in the direction it was feeding. Don't yank it sideways. If it tears, make sure you get every last scrap out. 4) Open the front door and check the paper path from the front too. 5) Reload your paper in the tray, making sure the stack is neat, the guides are snug against the paper, and you're not overfilling it past the mark. IF THAT DIDN'T WORK The sound might be coming from the print carriage itself if something is stuck in its track (see the "carriage jam" fix above). Check that path carefully. HEADS UP Always fan a new stack of paper before loading it to separate any sheets that might be stuck together from humidity. This is the #1 cause of multi-feeds and jams.

Question 6

just got a 4155e and the screen says 'carriage jam' but nothing looks stuck, what do i do?

Accepted Answer

DIAGNOSIS This is a common false alarm on these printers. It often means the print carriage (the part that holds the ink cartridges) can't move freely because a tiny piece of paper, a label, or even a bit of packing material is blocking its path inside. FIX 1) Turn the printer OFF using the power button on the back. 2) Open the front door and the ink cartridge access door. 3) Look deep inside. Use a flashlight. Check for any foreign objects in the track the carriage slides on. 4) Gently slide the carriage from side to side with your hand. It should move smoothly. If it's stuck, feel for the obstruction and carefully remove it. 5) Close all doors and turn the printer back on. IF THAT DIDN'T WORK Sometimes the error persists in memory. Unplug the power cord from the back of the printer for a full two minutes. Plug it back in and power on. This hard reset can clear the stuck error. HEADS UP Never force the carriage. If it truly won't budge, there might be a mechanical failure. Forcing it can break the plastic belt or motor.

Question 7

my hp deskjet 4155e says it's offline on my computer and won't print, how do i get it back online?

Accepted Answer

DIAGNOSIS This usually means the printer has lost its connection to your Wi-Fi network. The little wireless light on the printer is probably blinking or off. FIX First, let's get it back on the network. 1) On the printer's control panel, press the Wireless button (looks like a dot with curved lines). 2) Use the arrow buttons to scroll and select "Network" then "Restore Network Settings." Confirm. The printer will restart. 3) After it comes back on, you'll need to reconnect it. Hold down the Wireless button for 3 seconds until the light blinks, then go to your computer and run the HP Smart app. It should find the printer and guide you through setting it up on your Wi-Fi again. IF THAT DIDN'T WORK The connection might be blocked. Turn off your router and printer for 30 seconds. Turn the router on first, wait a minute, then turn the printer on. This often clears up the handshake between them. HEADS UP If you've changed your Wi-Fi password recently, the printer won't know the new one. You'll absolutely have to go through the reconnection steps in the HP Smart app.
