Probable CausesSolutions
The colors printed on the document do not match the 
ColorQube 8570/8870 printer PANTONE color chart.To match the document colors to the color chart:
• If the application software allows you to select a 
printer PPD file for printing a document, make 
sure the ColorQube 8570/8870 printer PPD is 
selected. The PANTONE colors in the printer are 
calibrated for the printer’s default halftone; 
overriding the printer’s default halftone will 
change the printer’s color reproduction. For more 
information about software settings for your 
applications, consult the application’s user 
manual.
• Turning off other color matching software, such 
as ColorSync or ICM color matching, when trying 
to match PANTONE Colors is recommended. 
Using other color matching software while 
matching PANTONE Colors can cause 
unpredictable color output. If you choose to use 
Color Management software, set the printer 
driver’s color correction to None, and do not use 
the printer-specific charts.
• To match PANTONE spot colors, in the PostScript 
printer driver, select Properties, click the Color 
Options tab, select Automatic color correction, 
select Custom from the drop-down list, then 
select Spot Colors.
For example, in the PostScript driver, set the color 
correction to None if the PANTONE Color chart 
was printed using None, the recommended 
setting. For details, see Adjusting Color 
Correction on page 103. Also verify that the 
color’s CMYK values match the CMYK values on 
the chart.
• The printed PANTONE charts can fade over time 
or when exposed to sunlight. Check the color 
charts you printed against the PANTONE Color 
swatch book available from PANTONE, Inc.
• You may need to re-print the chart, especially if it 
has been exposed to light for some time. Storing 
the charts in a dark place helps preserve the 
color.
• Print a test page from the control panel to check 
the colors. If the media in the printer is out of 
specification, or other supplies are at the end of 
useful life, color adjustments may not be able to 
get the printer to match PANTONE Colors.

1. On the printer control panel, select Tro u b l e s h o o t i n g and then press the OK button.
2. Select Print Quality Problems > OK.
3. Select Remove Print Smears > OK.
The printer prints several blank cleaning sheets as it goes through the cleaning process.
Eliminating Light Stripes
This procedure cleans the print head.
Notes:
•Do not perform the advanced Eliminate Light Stripes procedure without performing two 
basic Eliminate Light Stripes procedures first.
•Make sure the PostScript printer driver is set to Enhanced print-quality mode.
•Before running the Eliminate Light Stripes procedure, print the Light Stripes Test page to 
check for incomplete or missing ink jets. For details, see Printing the Light Stripes Test 
Page on page 173.
To clean the printhead:
1. On the printer control panel, select Tro u b l e s h o o t i n g and then press the OK button.
2. Select Print Quality Problems > OK.
3. Select Eliminate Light Stripes > OK.
4. Select Start Basic Clean Cycle > OK.
The printer will perform a printhead cleaning, which takes about five minutes. The printer then 
prints a cleaning page and a Light Stripes Test page. If the Light Stripes Test page looks good, you 
are done. If not, go to step 5.
5. Repeat steps 1–4. Examine the Light Stripes Test page that prints. If there are no weak or missing 
ink jets, you are done; if there are, go to step 6.
Note:Perform the advanced Eliminate Light Stripes cleaning procedure only once.
6. On the Light Stripes Test page, note the color and number of the weak or missing color stripe.
7. On the control panel, in the Eliminate Light Stripes menu, select Advanced > OK.
8. On the control panel, select the weak or missing color and then press OK.
9. Select the number of the weak or missing jet and then press OK.
The printer prints several cleaning pages.
10. After the cleaning procedure is complete, if the problem persists, perform another basic cleaning. 
If the problem is not corrected, try substituting a nearby functioning jet for the missing jet. For 
details, see Substituting an Ink Jet on page 173.

Printing the Light Stripes Test Page
The Light Stripes Test page helps you identify ink jet problems.
1. On the printer control panel, select Tro u b l e s h o o t i n g and then press the OK button.
2. Select Print Quality Problems > OK.
3. Select Eliminate Light Stripes > OK.
4. Select Light Stripes Test > OK.
Substituting an Ink Jet
This section includes:
•Enabling Jet Substitution Mode on page 173
•Disabling Jet Substitution Mode on page 174
When ink jets are not recoverable by cleaning the printhead, you can enable Jet Substitution to 
substitute adjacent jets to print in the area that is normally covered by the problem jet. Make sure to 
go through the printhead cleaning procedure before substituting any jets. For details, see Eliminating 
Light Stripes on page 172.
Note:Any jets that have been substituted will remain substituted until Jet Substitution mode is 
disabled.
Jet substitution requires the presence of any numerically adjacent, functional jet to replace the weak, 
missing, or discolored jet. For example, if Cyan jet 2 is missing, Cyan jet 1 or Cyan jet 3 can be 
substituted for Cyan jet 2, as long as jet 1 or 3 is not also weak or missing.
Jet Substitution mode will not correct situations where there are three or more consecutively numbered 
jets that are weak or missing. For example, if Cyan jets 1, 2, and 3 are all weak or missing, Jet 
Substitution Mode cannot be used for jet 2.
Note:When a jet is being substituted, a black dot is displayed next to its jet number on the Light 
Stripes Test page. Jet Substitution is only used when printing from a computer. Jet Substitution is 
not used when printing the Light Stripes Test page from the control panel.
A Service Mode key is printed at the bottom of the Light Stripes Test page. The Service Mode key 
summarizes the number of substituted jets for each color, for example, C:1, M:0, Y:0, K:0.
Enabling Jet Substitution Mode
1. On the printer control panel, select Tro u b l e s h o o t i n g and then press the OK button.
2. Select Print Quality Problems > OK.
3. Select Eliminate Light Stripes > OK.
4. If necessary, select Light Stripes Test to make a Light Stripes Test print that shows any weak or 
missing jet and the jet number.
5. Select Jet Substitution Mode > OK.
6. Select the color for the weak or missing jet and then press OK.

7. Select the number of the weak or missing jet (1 to 309) and then press OK to confirm the 
selection.
Note:If you need to substitute more jets, select Save Change and Select Another Jet and repeat 
steps 6 and 7.
8. Select Save Change and Exit > OK to complete the procedure.
Disabling Jet Substitution Mode
1. On the printer control panel, select Tro u b l e s h o o t i n g and then press the OK button.
2. Select Print Quality Problems > OK.
3. Select Eliminate Light Stripes > OK.
4. Select Jet Substitution Mode > OK.
5. Select Turn Jet Substitution Mode Off > OK.
Note:Any saved and stored jobs on the printer’s hard drive, if the hard drive option is present and 
enabled, must be resubmitted to print correctly while Jet Substitution is enabled.
