How to Identify and Fix Common Problems ?

Partial prints are a common issue with printers and there are several main reasons it can occur: Problem with the print spooler (on Windows PCs) Overload of the GPU on later model Macs. Dodgy USB cord.
Why Does My 3D Printer Stop Extruding Halfway? There are many reasons why your 3D printer might stop extruding halfway through a print. It could be due to the filament, incorrect temperature, a clog in the extrusion system and much more.
Remove any printouts or paper remaining in the printer. Load more paper. If this message appears during a print job, reset the printer by pressing the Pause button for 3 seconds, then load paper and send the job again.
Defective cables or communication ports can cause data loss. Printers rely on a properly formatted data stream to produce a page. Dropped or corrupted information packets sent over the network or through a defective cable interrupt the proper formatting of the stream and produce random output.
Check the Print Preview

If your page is showing a cut off or incorrect the print preview, it means that they page settings or margins are off somewhere. If you checked your software settings, it might be time to check your printer page settings.

This happens when the rollers or the transfer belt inside the printer get dirty or covered in excess dirt, ink or toner powder, and as the paper is moved through the printer the `tracks` are being left on the page. This is normally the case when the tracks on the page are located at either end.
3D print warping happens when extruded filament layers on the 3D printer build plate cool too quickly and shrink. This causes the plastic material to contract and pull away from the build plate, resulting in warping (or curling, as it is sometimes known).
The reason behind this problem is that some of the old material remains in the extruder due to the lower temperature needs of the new material. As a result, the old filament will not melt completely, and the residue left behind may cause the nozzle to clog in the long run.
Most common culprits for a clogged printhead are microscopic dust particles, air bubbles or dried ink. Running a printhead cleaning on your machine will clear the print nozzles of excess or dried up ink.
Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
Pages do not print / missing pages

Make sure that your page settings are set to print all pages and to print every page. Settings that cause some pages not to print are `manual duplexing`, `print every other page`, `print odd pages`, `print on both sides`, or similar settings.

The Print Spooler is software built into the Windows operating system that temporarily stores print jobs in the computer`s memory until the printer is ready to print them. In some circumstances you may need to stop and/or restart the service.
If the DC Controller turns on the laser beam continuously, the entire surface of the Photosensitive drum is neutralized causing a completely black page.
A Bad Toner Cartridge

Usually associated with compatible or re-filled cartridges, a leaky cartridge deposits toner inside your printer and onto your paper in places that it`s not intended, resulting in black spots.

Why Do Resin 3D Prints Fail Halfway? There are many reasons that can cause the resin 3D prints to fail halfway. It can be caused because of the wrong exposure time, unbalanced build platform, not enough support, bad adhesion, wrong part orientation, and many more.
Material stringing, missing layers, clicking sounds in your extruder gears, and inconsistent extrusion patterns—specifically thin layers—are all symptoms of a partially clogged nozzle. And if no filament is coming through your extruder onto the build platform, you could be dealing with a fully clogged nozzle.
Manually push the material out of the nozzle, once it has fully heated up. The material should slowly protrude out of the nozzle. If it doesn`t, this means your nozzle is clogged.
There are a few things that could be the cause of this problem, including: Empty ink or toner cartridges that need replacing. Ink or toner cartridges that have become dislodged from their proper place. The wrong paper size loaded in the input tray.
a misprint or misspelling in a text.
Shadow printing is a printing technique that creates a lighter shade of the text off centered to make the text appear to have a shadow beneath it.
Usually a quick paper setting adjustment will clear up a ghosting issue right away. Run a cleaning – Most printers have a cleaning function built into the machine. Run this a couple of times to attempt to clear up the printing issue. Inspect the drum – Sometimes excess toner powder can stick to the drum.
The sponge end of a blocked printer head can be cleaned with only one liquid other than water. This liquid is isopropyl alcohol. Isopropyl alcohol isn`t strong enough to melt the sponge but is still strong enough to dissolve the ink inside the blocked printer head.
Reasons why your HP printer has ink but won`t print

This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.

Adjust the paper size setting

Select your printer from the Printer drop-down list. Click Paper Size. Select the paper size that matches the size and type of paper loaded in the printer tray, and then click OK.

Prints blank pages, won't print from computer
ANSWER : 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.
