If a cyan, magenta or yellow outline appears around black letters on the OKI C532dn and the colored parts of an image are printed with an offset, first check the color registration using the printer’s internal pattern. Then run the automatic adjustment, and proceed to cleaning the LED heads and checking the print path only if necessary.<\/p>\n
Where to perform the actions<\/strong><\/p>\n Diagnostics and adjustment are performed using the OKI C532dn’s button-based operator panel and physically on the printer. Windows 11, Windows 10, the driver and color correction utilities are not required to correct a geometric offset between color layers. In the instructions below, output tray<\/strong> means the top cover of the print mechanism, not the rear output tray.<\/p>\n<\/div>\n This guide is intended for the OKI C532dn<\/strong>. The model may be displayed as OKI C532<\/strong> on the operator panel and in the software.<\/p>\n Do not use the menu path below for the OKI C332dn or C542dn. The C332dn has a different button-based operator panel and a common image drum unit, while the C542dn is operated using a touch panel. These models require separate instructions.<\/p>\n Do not start with a Windows test page: the application, driver and color profile may alter the result. The internal pattern is generated by the printer itself and allows you to check the color layers without a computer.<\/p>\n Examine the thin lines, the edges of the colored areas and the sections where the cyan, magenta, yellow and black elements are next to each other. If a colored outline or offset is visible on the internal pattern, the fault is in the printer. If the pattern is correct but the defect appears only when printing a particular file from Windows, check another document and restore the print job’s color settings to their defaults. Color Correct Utility and ICC profiles can change shades, but they should not be used to correct a physical offset between layers.<\/p>\n The OKI C532dn performs automatic registration adjustment when it is turned on and after the top output tray is opened and closed. Start with this standard and reversible operation.<\/p>\n If the colored outlines are now aligned, no further changes are required. Do not consider a slight difference in shade without duplicated edges to be the result of registration adjustment: shade and the position of the color images are different parameters.<\/p>\n If opening and closing the tray did not correct the offset, start the adjustment manually from the button-based operator panel:<\/p>\n Do not change adjacent settings to remove a colored shadow<\/strong><\/p>\n The Adjust Density<\/strong> command, the highlight, mid-tone and dark settings, and the C\/M\/Y\/K density values do not move the color images relative to one another. Do not change them at random or reset all settings.<\/p>\n<\/div>\n If the first manual adjustment noticeably reduced the offset, you can run Adjust Registration \u2192 Execute<\/strong> once more. If two consecutive adjustments produce the same poor result, repeating the process usually does not help identify the cause\u2014proceed to the following checks.<\/p>\n Contamination of an LED head may be accompanied by misregistration, but it more often appears as a vertical white stripe, a faded area or blurred letter edges. The C532dn has four LED heads.<\/p>\n Do not touch the fuser unit or use solvents<\/strong><\/p>\n The fuser unit inside the printer may be extremely hot. Do not touch the marked hot area. Do not clean the lenses with methyl alcohol, thinner, household cleaning fluid or compressed air: this may damage the lens surfaces and spread toner throughout the device.<\/p>\n<\/div>\n If necessary, you can see the location of the four lenses in the C532 LED head cleaning instructions<\/a>.<\/p>\n Proceed to this step if registration adjustment and cleaning did not help, or if the defect appeared immediately after clearing a paper jam, replacing an image drum or removing the belt unit. A foreign object in the paper path or an incorrectly installed belt unit may cause misregistration on the C532dn.<\/p>\n Prepare before removing the image drums<\/strong><\/p>\n Shut down the printer properly, disconnect the power cable and allow the hot parts to cool. Prepare a clean, flat surface and sheets of paper. The green image drum cylinders are fragile: do not touch them or leave the image drums in direct or bright light. Even under normal room lighting, complete the check in less than five minutes.<\/p>\n<\/div>\n Remove and reinstall the belt unit only if it was recently removed, is tilted, the cover no longer closes correctly or the display shows a belt unit installation error. There is no need to disassemble a properly working unit solely for a preventive check.<\/p>\nModels covered by this guide<\/h2>\n
