HP Color Inkjet Printer cp1700 - Internal Tests

Introduction

This document explains how to perform built-in internal tests for the printer. The internal tests include:
  • Printing a demo page.
  • Printing a calibration test page.
  • Printing a diagnostics test page.
  • Printing a test page for the two-sided printing module.
  • Printing a Skew Measurement test page.
Use internal tests to verify that the printer's internal firmware is functioning properly. Internal tests will not verify that the computer and printer connection is working properly. On the basis of the output of the test, the internal tests can be classified as:
  • Output - LCD Panel
  • Output - printout

How to initiate the tests

The internal tests are always started with the printer turned on. Hold down the POWER button while the taps are being done. The CANCEL button represents taps in multiples of ten, while the RESUME button represents increments of one. When the POWER button is released the test will finish. For example, to print the technical diagnostic page (15-tap test) the following steps are performed:
  1. With the printer turned on, press and hold down the POWER button and then press the CANCEL button one time, then press the RESUME button five times.
  2. Release the POWER button and the technical diagnostic page will print.

Before beginning the internal tests

  • Make sure that the printer's POWER light is on solid and that no other lights are active.
  • Make sure no error messages are displayed in the LCD.
  • The parallel or USB interface cable may remain connected to the printer during the internal test. If the internal test fails, remove the interface cable and try the test again.

Skew test - normal mode - A size - Tray 1 (71-tap test)

Skew occurs when the movement of paper in the mechanism is not square to the printhead movement. The result is inconsistent print margins along the paper’s edge (printing appears tilted on the page). The steps to perform the skew test are:
  1. Turn on the printer.
  2. Press and hold down the POWER button.
  3. Press the CANCEL button seven times.
  4. Press the RESUME button once.
  5. Release the POWER button.
  6. If the skew test needs to be stopped, press the CANCEL button.
  7. Without creasing the paper, fold the paper so that the skew test box, shown in Figure 5, next to the "C" located on the lower-left corner of the paper meets the skew test box next to the "A" located in the upper-left corner. Align the left edges of the paper.
    Figure : Skew test box
    note:
    The top and bottom edges of the paper will not be aligned when performing the test. The bottom edge (the edge with the "C") will extend past the top edge when the skew test boxes are aligned.
  8. Evaluate the print skew.
    1. Hold the folded skew test paper up to a strong light or a window. If the dark square in the center of the skew test box next to the "C" is contacting the dark square in the box next to the "A", the skew is within the product specification. No further testing is required.
    2. If the dark square in the center of the skew test box next to the "C" is NOT contacting the dark square in the box next to the "A", the skew is out of specification. Repeat the procedure on a second printout. If the skew is out of specification on the second printout, try the following:
      • Remove the paper and then reload it. Make sure the paper guides are snug against the paper and that the paper is snug against the right edge of the paper tray.
      • Check to make sure that only one type of paper is loaded in the paper tray.
      • Make sure the paper weight falls between 16 to 36 lb. Bond.
      • Try a different type of paper.
    3. If the problem persists, contact HP.
