User manual SHARP AR-C260

[. . . ] Ambient conditions (temperature and humidity) and the number of times the printer is used can have a large effect on colour deviation. The printer has two colour adjustment functions for the purpose of correcting deviations in the colour balance. These functions are executed from the key operator programs. [. . . ] *Processed grey is the colour obtained when the cyan, magenta, and yellow colours on the top line are combined together. 3 Checking the Colours The standard colour chart included with the printer is used to check the colours on the printed test page. Follow the steps below to check the colours. Test page (printed by the printer) Standard colour chart (included with the printer) C Low Density M Y Bk C Mid Density M Y Bk C High Density M Y Bk Low Density Mid Density High Density Place the colour chart on the printed test page as shown. Check the density of the colours on the test page and see if they are adjusted to the same level as the colours on the standard colour chart. Low Density Mid Density High Density If the result of the comparison is that: · There is a large deviation in the colour densities use the Colour Balance settings (see the following page). · There is a small deviation in the colour densities, use Easy Calibration (see 7 page). 4 Using the Colour Balance Settings The colour chart included with the printer is used to adjust the Colour Balance settings. Follow these steps to adjust the settings using the operation panel. NOTE: · Keep the Colour Chart in the place near printer. · Do not expose the Colour Chart to direct sunlight. Colour balance is the utility to set the print image to the recommended status. But if you do not feel the image is distorted, you need not use colour balance. 1 Enter the key operator programs. To enter the key operator programs, see "Using the key operator programs" on page 3 of the Key Operator's Guide. After a brief interval, Test Pattern1 will be printed (see the following page). 6 Place the colour chart on Test Pattern 1, compare the colour densities, and then adjust the colour balance in the following screen. For a detailed explanation of adjusting the colour balance, see "Adjusting the colour balance" on the following page.

Your settings will be saved and you will return to the Colour Setting screen. Print a test page as explained on page 3 and verify that the colours match the colours in the standard colour chart. The processed grey on the bottom line of the test page provides a good indicator of the colour balance when performing fine adjustment of the colour densities. EXECUTE When the [EXECUTE] key is touched, "SELF PRINT IN PROGRESS" appears in the display. 5 Adjusting the colour balance (additional information for Step 6 on the previous page) Test pattern 1 (printed by printer) C Low Density M Y Bk C Mid Density M Y Bk High Density C M Y Bk Colour Chart (included with printer) Column 1 Column 12 Colour density level 1 Place the colour chart on test pattern 1 and compare the colours. For the placement of the colour chart, see page 4. 2 In column 1 of test pattern 1, locate the colour density level that is the same as "1" in the colour chart. Mark that level with a pencil or pen to help you remember it. [. . . ] (see the following page). 7 Easy Calibration (additional information for Step 6 on the previous page) Easy Calibration is performed by selecting the desired colour of grey (processed grey), which is a combination of cyan, magenta, and yellow. Test Pattern 2 (printed by printer) Test Pattern 3 (printed by printer) Magenta (-3~±0) Magenta (±0~-3) Example:if this is the desired colour, select "+1" for X and "+2" for Y. Yellow (-3~+3) Yellow (-3~+3) Test patterns 2 and 3 indicate processed grey colours with the current grey colour as the reference point or origin ("0"). · The X axis shows the density of magenta in seven increments from -3 to +3 (-3 to 0 in test pattern 2 and 0 to +3 in test pattern 3).
