The 1020 driver itself is loaded, and as far as I can tell, all the components you have mentioned are installed and active, they just don't print.

I’ve found that majority of the time I find myself using this feature is on color machines becasue it helps show how the DC controller is seeing the color planes.I downloaded the latest version of CUPS without using the SPM, and although the install script ran, it asked for a number of other packages to be installled manually, which is beyond my ken.(I don't know how to do it! ) If the engine test is then successful, the problem is almost certainly with the formatter, the control panel, or the cable that connects them.Īlright, hopefully this article has helped you find the test button location and has given you a better understanding of the use of the button. If the engine-test page does not print, try removing the formatter and performing the engine test again. NOTE A damaged formatter might interfere with the engine test. The printer will not print a test page if it is in PowerSave or Sleep mode. The printer will continuously print test pages as long as the test-page switch is depressed. However, if the printer has been turned off and then on again since the most recent print job, the page will print from tray 2. The test page prints from the last tray that you printed from. The test page should have a series of vertical lines.

Use a small, non-metallic, pointed object to depress the test-page switch, which is located on the right side of the printer. To verify that the printer engine (all printer components except the formatter, formatter DIMMs, EIO products, and the stacker or stapler/stacker) is functioning, print an engine-test page. Before printing this test page I always recommend using the information menu and print off a config page first because that’s the best way to start troubleshooting print problems. Using the engine test button is not as common as it use to be put in frustrating situations it can be a life saver.

Pretty much if you’re having unexplained poor print quality, all black, blank, other odd print, or odd error codes when printing using the engine test button by-passes several components on the formatter and just strictly test the print engine so you can focus on other parts of the machine. Printing test pages helps you determine whether or not the printer engine and the formatter are functioning. HP Laserjet 4250, 4350 Printer Engine Test Button Location
