When HP Smart displays the “Printer status unknown” error, the app can`t communicate with your printer. Issues with your printer connection, firmware, or driver are often responsible for this error message.
If your USB printer is not found by the HP Smart app, make sure Windows is up to date, check for USB connection issues, and then reinstall the app. Note: An HP+ or eligible printer cannot enroll in HP Smart Advance or Instant Ink using a USB connection.
Status unknown means a circumstance where samples were scheduled to be taken by the regional water quality control plant and were not, samples were taken but not yet analyzed by the report due date or where a new discharger has yet to be sampled.

Prints blank pages, won't print from computer
Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work. Just because you reinstalled a connector doesn’t mean that it is seated firmly enough to work. Any flat ribbon connectors that you removed and reinstalled, check to see that the contacts are all flat and not peeled back.
when printing front and back, the front will print well but the back will fade
It happens because second side voltage is much higher and the board breaks. Are you getting this issue in auto duplex only, or same error you are getting when you print second side manually?
Print file sent but no printing occurs
Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.
HP Laserjet 4100 Error (13.1)
I am pretty late to the party for this discussion but I am incredibly thankful to the person that posted this “fix” that I can barely imagine it. My 4100 had developed the dreaded paper jam described above and I had no idea what was causing it. I replaced a number of rollers only to have the same problem re-occur with no solution in sight.
My printer feeds through one piece of paper all the way and then a half piece of paper and stops. I pull out the paper to stop the paper jam and then it prints but sounds rough. After printing, it doesn't feed the paper all the way through.
And the first 2 sheets, the full and half sheet that go through first, are blank.
Paper feeds straight through without printing on an Epson R2400
I was able to get it to print the internal test page by holding down the sheet paper feed button while turning the machine on — then continuing to hold the sheet paper feed button. It took several attempts, feeding a page straight through, but eventually it caught the sheet and printed. So it may be a timing issue as others have mentioned. It could still mean that the feed rollers are worn out. The back side of the large D-shaped feed roller has visible abrasion on it. The abrasion is difficult to see as the roller does not stay with the flat side exposed.
Epson Artisan 835 print head cleaning question
I had the same problem. After reading the comments, I tried Liquid Wrench spray. 1st try got about sixty percent improvement. Tried again this time I let it set for about 10 min then did a head cleaning. Completely solved the problem. I am a little concerned about its use on plastic. So far so good.
My printing come out blurred
doris…There are usually 2 reasons for blurry output on this printer. First, make sure that the alignment is correct. You can get to it from the maintenance tab on the software that came with the printer. The other common cause of blurring is debris under the printhead. Hope this helps.
