HP Deskjet 5740 - Troubleshooting Print Quality Problems with the Diagnostic Page

Problem

The printer is working, but the printed output is not what y'all expected. The color may not wait right, it might be streaked or faded, the ink may take smeared, the image may expect crooked, or there may be other problems.

Solution

Impress and evaluate a diagnostic page to find out if your printer or print cartridges are causing the trouble.

Step 1: Impress a diagnostic page

Brand sure the printer is on and loaded with unused, plain, white newspaper.
Press and hold the Power push, then click the Cancel button once. Then release both buttons. The diagnostic page prints.

Step two: Note which cartridges printed which areas of the diagnostic folio

Place which cartridge printed which part of the diagnostic page, then that if y'all observe defects on the page, you know which cartridge is the problem.

However, you tin can install dissimilar combinations of ink cartridges in your printer, and different cartridge combinations print different diagnostic page patterns. The diagnostic folio might not look exactly like the example presented hither, but the correct and left cartridges print in the same areas of the page no matter which cartridges are installed.

note:
If you are printing in reserve mode (one cartridge is missing), the expanse of the diagnostic page where that cartridge prints is bare.

Step 3: Check ink levels

notation:
If yous have installed a refilled or remanufactured ink cartridge, or a cartridge that has been used in another product, the ink level indicator is inaccurate or unavailable.

Look in the heart of the diagnostic page. The bars with "East" (for "empty") and "F" (for "full") at each end evidence the ink levels in the cartridges. As ink is used, the solid color changes to a faded colour.

Figure : Both left and right cartridges almost full

Stride 4: Expect for defects

In general, if the printer and ink cartridges are working properly, the patterns (which await similar grids of lines) should comprise few or no missing lines. Also, the colors of the patterns and confined should exist approximately the aforementioned as the color dots on the ink cartridge label.

notation:
Practice non compare the colors on your diagnostic folio to the colors on this Web page. Unless your monitor is calibrated, the colors will not exist correct. Instead, compare the colors on the folio to the colored dots on the ink cartridge label. While the color dots may not be perfectly accurate, they are likely to be more accurate than the colors on the monitor.

Missing lines or streaked confined

If a pattern shows more than a few missing lines, or a bar is streaked, that ink cartridge is not functioning properly.

Figure : The left cartridge (a tri-color cartridge) shows missing lines and a streaked bar - the cartridge is not functioning properly

Colors practice not lucifer the color on the cartridge characterization

If the color of the patterns or bars is very different from the color dots on the cartridge label, the cartridge is non functioning properly.
