Has your printer ever printed out something that is faded, smudged, or streaky, making it absolutely useless? You’d probably be wondering how that happened and what caused it. Well, this post is for all of you out there who are wondering the same thing. I’ll explain what can cause bad print quality, as well as what you can do about it.
First things first, let's see if we can eliminate some of the more common problems that can be causing the print-quality issue.
Your printer may have a troubleshooting print-quality page you can print out to help identify, troubleshoot, and solve specific issues. If so, print it out and see if any of the issues described match the problem you're encountering. If your unit doesn't have one, no worries! Let's continue to narrow down some possibilities.
Your paper may be the problem.
Unsupported or damaged paper can cause print-quality problems even when the printer, application, and print driver are working perfectly. To eliminate paper as the source of your issue, try the following:
Make sure your printer supports the paper or media you're trying to use.
Make sure the printer is loaded with undamaged, dry paper.
If you're unsure about the condition of your paper, replace it anyways.
Make sure that the proper tray is selected in both the print driver and from the control panel.
Make sure that the correct paper type is selected in both the print driver and from the control panel.
Is the printer the problem or the application?
If your printer has it, try printing out the troubleshooting print-quality page or a similar test page.
If the pages printed properly, the printer is working properly. This means the problem is an application, print driver, or print server problem.
If the pages have print-quality issues, then the printer is the problem.
So, the issue is with the application, print driver, or print server.
If the printer is printing properly from the control panel, but when you try to print there are still print-quality issues, the application, print driver, or print server may be the root cause. To figure out the issue:
Try printing a similar document from another application and see if the same print-quality problems repeat.
If the document has the same print-quality issues, it is likely a print driver or print server problem. Check the print driver used for your print job.
Navigate to the list of printers on your computer.
Right-click on the name of the printer.
From the drop-down list, select Properties.
Ensure that the model name in the driver matches the model name of the printer you are using.
If the names do not match, install the proper printer driver for your printer's model number.
If the print driver is correct, try to reset your printer's print quality mode, as well as the color correction.
If the problem persists, delete then reinstall the print driver.
If the document printed without a print-quality problem, the application is likely the cause.
Restart your printer, restart the application, then try printing the document again.
So, the printer is the issue.
If you have print-quality problems when printing a demo page or configuration report from your control panel, the problem is the printer.
The next step is to identify the type of problem you are encountering. Included below are common print-quality issues with their solutions.
