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.
Check the print job settings: From the application you are printing from, click File > Print, and then click Options, Printer Setup, or Preferences, or open the Paper Type/Quality or Media & Quality menu. Make sure the color, paper type, paper size, and quality settings are correct for your print job.
The streaks or lines might be caused due to low ink levels in one or both ink cartridges. Check the ink levels using the HP Toolbox to determine if the ink cartridges are low on ink and need to be replaced.
Defective ink or toner cartridges are one of the most prevalent causes of ink smudges or faded prints. Check to see if all of your ink cartridges are still in good working order. Check that the ink hasn`t dried out and that it`s clear of debris and residue.
All bars glow blue when the printer is in the process of connecting to your wireless network. Blue light moves from the center to the outer edges: The printer is in Auto Wireless Connect (AWC) mode and is waiting to connect to your computer or mobile device.
For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water. Note: If dark spots appear on back side of prints, clean drum screen. Note: If minilab prints more than 2000 prints each day, clean drum screen up to twice daily.
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.
Why is your printer printing pink? Your printer may be printing pink as the other ink cartridges have run out. Common printer-to-page technology processes colour in four parts; cyan, magenta, yellow and black (CMYK), or toner. The ink cartridges in your inkjet or colour laser printer are split up into four colours.
verb. If you smudge a substance such as ink, paint, or make-up that has been put on a surface, you make it less neat by touching or rubbing it.
Red and green light produces Yellow, the second subtractive primary, and blue + green = Cyan, the last. Printers quickly realized that making black by mixing all 3 subtractive primaries was a messy business, so they standardized on a 4-color palette: Cyan, Magenta, Yellow, and Black.
The Edge light bar glows purple when the printer is connecting to a Wi-Fi network. Purple light moves from the center to the outer edges: The printer is in Auto Wireless Connect (AWC) mode and is waiting to connect to your computer or mobile device.
Printing blues can be tricky because it is very close to purple within the CMYK spectrum and often times there is too much Magenta mixed in with the Cyan. If your design is coming out too purple, the key rule of thumb is to make sure to leave at least a 30% difference in your Cyan and Magenta values.
You can visually inspect the remaining cartridge levels on your printer. If they are full but you still cannot print properly, check the cartridge`s expiry date. Expired ink cartridges often dry up which causes problems in the print results.
Replace any low, empty or faulty ink cartridges on your printer. Dust or paper residue on the rollers or separator pad inside the automatic document feeder (ADF) can result in copy quality issues.
