1. Perform the Sensors Test. See Sensors Test on page 149.
2. Check that the cable for the faulty sensor is not damaged and is connected correctly.
3. Replace the faulty Sensor.
The line sensor has problems detecting paper
1. Check the type of paper that is being used since the Line sensor may have problems detecting
transparent paper or some types of Non-HP paper. Try loading white HP paper in to the product
and check that the Line sensor detects it.
2. The Line Sensor is not calibrated correctly. Perform the Line Sensor Calibration. See
Line Sensor
Calibration on page 228.
3. The Line Sensor is damaged or faulty. Replace the Line Sensor. See
Line Sensor on page 424.
12 Chapter 1 Troubleshooting ENWW
Troubleshooting Printer paper jams and printhead crashes
The failure modes "paper jam" and "head crash" are grouped together because in many cases a
paper jam causes the paper to lift up into the Carriage path and cause a Printhead crash, thus causing
many paper jam failures to be reported as head crashes.
1. Did the paper jam occur when loading paper?
●
If the client has had paper jams, it is common for pieces of paper to get stuck in the paper
path. Clear the paper path.
NOTE: When clearing a paper jam, sometimes paper is stuck in the paper path. To clear this,
you must lift the Media Lever and insert thicker paper into the paper path to push out the paper
that is still stuck there.
2. Is the customer using non-HP paper?
●
The use of non-HP paper can easily be the cause of paper jams and head crashes (especially
head crashes because HP paper is specially formulated to avoid cockle, one of the primary
causes of head crashes). If the paper is not HP approved, advise the customer to use HP
paper and check to see whether the problem is now solved.
Troubleshooting Scanner paper jams (MFP only)
1. If while feeding paper into the Scanner a jam occurs, use the eject button on the Touch
Control Panel to clear the jam.
2. Unlatch the CIS Cover.
ENWW
Product Troubleshooting trees (MFP)

3. Open the CIS and clear the area of any paper.
The basket was damaged during the product setup
1. There are three plastic parts that could break during product installation and need replacing.
2. Check the parts table and graphics in Parts and Diagrams to identify what service parts you must
order. See
Product Support on page 241.
3. Replace the component. See
Bin Assembly on page 280.

Paper-handling troubleshooting
Roll paper The Touch Control Panel of the product indicates that paper is misaligned or incorrectly positioned
●
The roll may be loaded the wrong way. The paper should load over the roll toward you.
●
Check that the paper is correctly loaded onto the spindle.
●
The paper may be loaded at an angle. The right-hand edge must be aligned with the blue line on the
Print Platen.
●
Check that the Right Roll Support is properly attached and screwed to the product.
●
The Rewinder, located on the Right Roll Support, should maintain proper back tension. If the Right Roll
Support is misaligned or not properly attached to the product, the Rewinder will not function properly.
●
To further diagnose problems with the Rewinder, see
Rewinder Test on page 151.
●
If the customer is experiencing problems with paper jams, check that the Overdrive is not obstructed by
paper or that the Turn Drive Roller Service Utility is being used. See
Turn Drive Roller on page 177
●
While attempting to load roll media, if the Touch Control Panel prompts you to remove paper, although
no paper is loaded, calibrate the sheet sensor, refer to
Calibrate Sheet Sensor on page 232
Sheet paper
●
The sheet must be loaded with the right-hand edge against the white line on the upper roll cover.
●
The paper may be crumpled or warped or may have irregular edges.
●
If the printer incorrectly detects the presence of a sheet of paper, perform the Calibrate Sheet Sensor,
refer to
Calibrate Sheet Sensor on page 232.
●
If hand-cut paper is used, the edges may not form a right-angle or they may be rough. If possible,
hand-cut paper should not be used. Only purchased sheet paper should be used in the product.
●
If you have problems with paper jams, check that the Overdrive is not obstructed by bits of paper or
using the Turn Drive Roller Service Utility. See
Turn Drive Roller on page 177.
●
When attempting to load sheet paper from Front Panel, if the printer displays a media skew message
repeatedly, and sheet cannot be loaded, calibrate sheet sensor. refer to

Introduction to ink supplies
What are ink supplies?
For each of the ink colors used in the product, there are two components, the Printhead and Ink
Cartridge. These components are called Ink Supplies.
Ink cartridges
The product's six Ink Cartridges provide matte black, magenta, yeloow, cyan, gray and photo black ink
to the Printheads. The color Ink Cartridges supplied with the product have a capacity of 69ml but
optional 130 ml are also available.
All these Ink cartridges are physically the same size. Only the internal capacity varies.

The Ink Cartridges for the T product series require no maintenance or cleaning. As long as each Ink
Cartridge is inserted correctly into its slot, the ink will flow to the Printheads. Because the Printheads
control the amount of ink transferred to the page, you will continue to see high-quality printing results
even when the ink levels are getting low.
The Touch Control Panel displays the status of the Ink Cartridge. Using the Touch Control Panel,
detailed information can be checked on the Ink Cartridges.

Printheads
The Printheads are extremely durable and do not need to be replaced every time an Ink Cartridge is
replaced. They are independent of the Ink Cartridges and will continue giving excellent image-quality
results even if the Ink Cartridges are low on ink.
