Dirt and debris on the paper path rollers can cause print quality issues. Use the blue Smartsheet® from the same pack of HP Sprocket Photo Paper currently in the printer to clean the paper path rollers. NOTE: To avoid print quality issues, do not use a Smartsheet® from a different pack of HP Sprocket Photo Paper.
The “tiny corner” printing might be the result of the “Page Setup” > Scale being set to other than 100%.
Click Start, point to Settings, and the click Printers. Right-click the appropriate printer, and then click Properties. Click the Paper tab, and then click the paper size you want to use in the Paper Size box.
If you notice that your print quality is uneven, too light, too dark, or there are vertical or horizontal lines in the print (banding), try these solutions: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary.
Printers are configured in the Printers section of the Windows Control Panel. Printer Settings: Displays the printer settings window associated with the selected printer. The desired paper size, among other settings, can be selected in the printer settings window.
Technically, the Sprocket Select uses ZINK printing technology and sticky-backed photo paper that measures 2.3 x 3.4″, and the printer has a resolution of 321 x 600 dpi.
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.
Start by choosing “File” and then “Print,” and clicking the “Position and Size” settings. Usually, the default option is “Scale to Fit Media,” which prints to the page margins. Deselect it, then manually enter scale, height and width values that equal the full size of your paper. Click “Print” to print your image.
A common cause for images to be of low quality is when it is enlarged without proper tools. Increasing the size of the image can often result in the photo losing its quality and resolution to drop significantly.
The most common cause of blurry high resolution photos is motion blur, but camera settings and shooting environment/conditions can cause them as well. In addition, some causes are specific to printing on products and details on those follow.
For instance a 300 DPI image corresponds to 300 (length) x 300 (height) pixels image, which means 90 000 pixels.
To convert a picture to high resolution, you can use an image upscaling tool like Upscale. media. Upscaling is a process that increases the size and resolution of an image while trying to maintain its quality. Yes, a JPEG can be high resolution.
Select Start > Settings . Go to Devices > Printers & scanners > select a printer > Manage. Then select Set as default. If you don`t see the Set as default option, the Let Windows manage my default printer option may be selected.
PDF is the most commonly used file format for printing documents and graphics. PDFs are easy to share, but not easy to edit. To edit the text in a PDF, you`ll need to convert it to another file type, like a DOC.
To resolve most print quality issues, use genuine HP cartridges, and in some cases, you might need to allow the printer to complete the automatic servicing routine. Check the paper and print settings to make sure that they are correct for the print job, and clean the cartridges and printhead.
A printer test page is one of the easiest and most effective ways to analyze and calibrate your printer`s performance. Test pages often include text, graphics, and images that, when printed, aim to maintain the health of your printer (and cartridges) while highlighting any issues that your printer may be having.
Both RGB and CMYK are modes for mixing colour in graphic design. Monitors use RGB whereas printers use CMYK. This means that RGB colour mode is best for digital designs, while CMYK is best for print materials.
The printing modes are settings that act on different printing parameters like the temperature of printing and cooling and printing speed in order to provide better mechanical resistance to the parts.
As a rule of thumb, to achieve photo quality print, you will need to use an image resolution of 300 pixels per inch. We write this as 300 DPI and means that in each inch of your print there will be 300 pixels.
Remember, you should never print your images at the same resolution as your screen. These are typically 72 DPI (dots per inch). So you want to aim for anything between 300 and 1,800 DPI when printing.
A standard resolution of 300 dpi is acceptable for most text-based documents, while 600 dpi or higher is better for detailed photo scans.
What is printer calibration? Calibrating a printer ensures that the inkjet cartridge nozzles and printer paper are properly aligned to each other. This process ensures that colours stay rich, clear and the finished result is of the highest quality.
Right-click the desktop, and then click Display settings or Screen resolution. If you have more than one display, click the image of the display you want to adjust. On the Resolution drop-down menu, select the desired resolution, and then click Keep changes, OK, or Apply.
It prints out 2 x 3-inch photos on special sticky-backed paper so you can use the prints as photos or stickers.

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.

Print file sent but no printing occurs
ANSWER : 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.

Laserjet 4250 print quality issue (see image)
ANSWER : It looks like a fuser problem. One way to prove it is with the half-stop test. Put a sheet in the drop down manual feed tray. Send a print job and watch the paper. When the end of it is about to enter the printer, open the lid and take out the toner cartridge. Look at the printed image. If it looks OK, then it is a fuser problem. If not, then it is a toner cartridge issue since it hasn’t gone through the fuser.

Printer won't print – reassembled from an imaging unit clean..
ANSWER : You have to realize the difficulty of troubleshooting a printer that an unexperienced person has taken apart. The pickup roller issue doesn’t sound like it is a worn pickup roller. It seems more like something wasn’t quite put together and is binding the drive motor. Since I can’t hear it or see it, that would be my best guess.

Paper feeds straight through without printing on an Epson R2400
ANSWER : 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.
