If your Sprocket printer is printing out blank photos, the most likely explanation is that the paper is not loaded properly in the printer. The paper may not be aligned properly, it may be upside-down, or it may be the wrong kind of paper for your Sprocket.
Clean the print head, if necessary. Make sure the paper size, orientation, and layout settings in your printer software are correct. Make sure your document does not contain blank pages. If your printer software has a Preview option, you can check for blank pages before you print and remove them, if necessary.
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.
If your printer is spitting out pages full of strange characters, symbols, or strange formatting, your inkjet printer drivers may be outdated, incompatible with your operating system or corrupt. Drivers are important to the proper function of your inkjet printer and it is best to check for updates regularly.
No ink required

By utilizing innovative ZINK™ technology, all you need to print your next photo is the HP Sprocket Photo Paper. ZINK™ technology works by activating dye crystals within the photo paper to give you the same color accuracy as ink without worrying about cartridges.

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.
Check the Margin settings under File>Page Setup to make sure that the right margin is OK. Also check the paragraph format to make sure that you do not have a negative right indent which could be causing the text to extend into an area that is unprintable by your printer.
Printers that use two cartridges (one black, one tri-color) can print if one cartridge is empty. To continue printing, remove the empty cartridge from the printer. If a Single-cartridge mode message displays, select OK. If you are using the black cartridge, prints are in black and white (grayscale).
Make sure that the printer cable is not too long. We recommend that you use a USB cable that is no longer than 2 meters (6.5 feet). If you use the USB cable that is longer than 2 meters (6.5 feet), change it to the shorter USB cable and try again. Make sure that the printer cable is not damaged or broken.
Dots are typically caused by foreign material inside the machine (for example paper dust, glue from labels or envelopes, paper clips, staples) sticking to or damaging the surface of the drum. Toner builds up on or sticks to these areas on the drum and creates black dots on the printed pages. 2.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
If the ink level is sufficient, but the printer still does not print black ink, you may need to run a cleaning cycle. A cleaning cycle is a process that cleans the printer heads and removes any clogged or dried ink.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
