General information 1-7

Most paper jams can be avoided by correctly loading paper and specialty media in the printer.

The following hints can help prevent paper jams:

• Use only the recommended print media.

• Do not overload the print media sources. Make sure the stack height does not exceed the maximum height

indicated by the stack line on the labels in the sources.

• Do not load wrinkled, creased, damp, or curled print media.

• Flex, fan, and straighten print media before loading it. If jams do occur with the print media, then try feeding

one sheet at a time through the manual feeder.

• Do not mix print media sizes, weights, or types in the same print media source.

• Push all trays in firmly after loading them.

Note: Make sure the media stack is below the maximum media fill indicators on the 250-sheet tray before

pushing the tray into the printer.

• Make sure paper guides are positioned before loading the paper or specialty media.

• Do not remove trays while a job is printing.

• Before loading transparencies, fan the stack to prevent sheets from sticking together.

• Do not use envelopes that: – Have excessive curl – Are stuck together – Are damaged in any way – Contain windows, holes, perforations, cutouts, or embossments – Have metal clasps, string ties, or metal folding bars – Have postage stamps attached – Have any exposed adhesive when the flap is in the sealed position

•

Use only recommended media. Refer to the Card Stock & Label Guide available on the Dell Web site at www.dell.com for more information about which media provides optimum results for the current printing environment.

Paper jam error codes (200-series)

Note: The Event log (See “Event log” on page 3-14) will list any of these errors that have occurred.

Repeating jams or jam messages can be caused by any of the following:

• Faulty/contaminated pick solenoids or worn cams of the solenoids.

• Faulty/contaminated flags or springs.

• Debris in the paper path.

• Media not of the specified length.

Error Description Action

200.00 Paper jam around input sensor. Remove the PC kit and paper or debris at the input

200.01 Classic input jam. The media is too long over the input sensor. Possible causes include multi-sheet feed, tray size sensing problem, and media slippage.

200.02 The main input sensor never became uncovered from the sheet ahead.

200.03 The video never started on the page at the input sensor within two inches after hitting the input sensor

200.04 The media at the input sensor before interrupt occurred–not enough time elapsed since the printhead started to expect the printhead mirror motor lock. Possible causes include bouncy sensor or exceptionally fast pick– perhaps due to media prestaged in the source tray.

200.06 Imaged page not expected page (bouncy passthru sensor)

200.08 Media reached the input sensor before the EP was ready

200.09 Transfer servo never started Inspect the LVPS/HVPS. See “Controller board

sensor.

First, remove the PC kit and paper or debric at the input sensor. Then, inspect the flag on the input sensor. It should rotate freely. Replace the sensor if necessary. Finally, check the paper size settings in the printer and the driver.

Check the printhead. See “Printhead service

check” on page 2-37.

Carefully remove the tray and notice if the leading edge of the media is pointed upward and out of the tray. If so, then inspect the tray wear strips and replace if necessary.

Inspect the input sensor flag and replace it if it does not rotate freely or is too loose.

Remove the toner cartridge/PC kit. At the front, remove the upper front guide, and inspect the flag on the manual input sensor. If the flag is loose, then replace it. See “Media manual input sensor

removal” on page 4-39.

Inspect the tray for prestaging. Verify the proper media and inspect the tray wear strips. Replace the wear strips if necessary.

Error Description Action

200.13 The input sensor is covered when the media is not expected (media in machine during warm-up)

200.14 Trailing edge cleared manual feed, but did not successfully debounce the sensor. Potential causes are a small gap or a bouncy manual feed sensor.

200.15 UNRECOVERABLE NO GAP JAM. Engine detected no gap at the manual feeder sensor, attempted to open the gap by stopping the feed rolls, but no trailing edge was ever seen at the input sensor.

200.16 Transport motor error detected Inspect the main motor. See “Main motor service

Remove the toner cartridge/PC kit, and inspect for debris in the paper path. Check the bottom of the PC kit for any obstructions. Remove the upper front guide, and inspect the pinch rollers.

200.20 The media is too long over the manual feeder sensor. Possible causes include multi-sheet feed, media size (length) problem, pre-staged media in the tray.

200.22 FAILED SMALL GAP OR NO GAP JAM RECOVERY. Engine detected small gap or no gap at the manual feeder sensor, opened the gap by stopping the feed rolls, but never saw the leading edge of the second page at the input sensor.

200.23 Laser Servo never started due to potential conflict with the transfer servo. Possible causes: slow or missing transport motor positional feedback, or the media is transferred too quickly to the input sensor.

200.24 The measured gap at the input sensor is too small to meet the video delivery requirements. (There is not enough time since prior image finished to start new image)

200.26 The trailing edge never cleared the input sensor when feeding out the media that was detected during warmup.

200.27 Printhead Driver: Mirror motor fell out of lock condition after the media at the input sensor–more time elapsed since the printhead than the expected stable lock time, but less than the printhead jitter-stable specification.

Mirror motor fell out of lock condition after media at the input sensor–more time elapsed since the printhead than expected stable lock time, but less than the printhead jitter-stable specification.

200.30 Narrow media sensor covered during warm-up. Check that the narrow media flag rotates freely and

200.32 Media more than 14 inches too long over the manual feeder sensor. Possible causes include multi-sheet feed or pre-staged media in the tray.

200.33 Page from tray 1 did not reach the input sensor after multiple attempts. Page did make it out of the tray at least as far as the manual feeder sensor. Possible cause is that the page stalled at the alignment gate.

200.34 Timed out waiting for page from tray 1 to reach the input sensor after multiple pick attempts, but the page was later detected at the input sensor while waiting for any page(s) ahead to clear the paper path. Possible cause is that the page is delayed at the alignment gate.

Service checks

Service checks which involve measuring voltages on the LVPS/HVPS (low voltage power supply/ high voltage power supply board) should be performed with the printer positioned on its back side.

Note: When making voltage readings, always use frame ground unless another ground is specified. See the wiring diagram in the back of the book for more information.

Controller board service check

FRU Action

Controller board assembly

Warning: Do not replace the operator panel and controller board at the same time. Each card contains the printer settings. When either of these cards is new, it obtains some of the settings from the other card. Settings are lost when both are new and replaced at the same time.

POST (Power-On Self Test) Note: The printer should complete POST in approximately 30 seconds.

If the printer fails to display lights or activate the drive motor, fuser, or fan, then check the following in order:

1. Power to the LVPS/HVPS Turn the printer on and listen carefully for a click near the switch. A clicking sound

verifies that the outlet and power cables are good. Absence of a clicking sound may indicate a lack of power supplied to the LVPS/HVPS.

2. Power from the LVPS/HVPS to the controller board With the power on, check the LED below the right lower corner of the fan. If the LED

lights up, it indicates that power is supplied to the controller board. If the LED does not light up, proceed to the next check item.

3. Cables correctly plugged, especially for the operator panel The printer will not power-up without a functioning operator panel even with a lighted

LED on the controller board.

4. The controller board assembly The LED adjacent to J12 will be illuminated if the card is powered and good.

5. The operator panel See “Operator panel service check” on page 2-27.

Verify +24 V dc input from the LVPS/HVPS.

1. Turn the printer off.

2. Disconnect the LVPS/HVPS cable from the controller board at J502.

3. Turn the printer on.

4. Verify +24 V dc on positions 6, 17, and 19 of the cable connector (LVPS/HVPS). If there is no voltage supplied on any of these positions, turn the printer off and go to step 7.

5. Verify +5 V dc on positions 1, 3, 4, 5, 11, 13 and 15 of the cable connector (LVPS/ HVPS). If there is no voltage supplied on any of these positions, turn the printer off and go to step 7.

6. Turn the printer off. Check the continuity of the conductors of the cable and the card connector with respect to ground. Verify that pins 10, 12, 14, 16 and 18 on the cable are grounded. Verify the same pins on the card connector side are grounded too. If there is no continuity on any of the card pins, verify that all the mounting screws are tight. If there is still no connection to ground then replace the controller board. See “Controller

board removal” on page 3-6.

7. Open the LVPS/HVPS and disconnect the controller board-to-LVPS/HVPS cable at CN201.Verify continuity in each conductor of the cable. This cable is not a replaceable part. If continuity is still not good then go to “Dead machine service check” on

page 3-24.

2-22

Controller board voltage outputs Turn the printer off, and plug the LVPS/HVPS cable into J502 of the controller board. See

the wiring diagram at the end of the manual which identifies the output voltages and grounds for a good controller board.

Turn the printer off before plugging or unplugging any connectors.

Controller board service check (Continued)

FRU Action

LVPS/HVPS Verify main power to controller board

With the printer off, unplug the LPS/HVPS cable at J502 on the controller board. Verify grounds on pins 10, 12, 14, 16 and 18 for both the cable and the controller board. If any of these grounds are incorrect, then check the cable for continuity. If the cable fails continuity, then call the next level of support.

Turn the printer on with the cable still unplugged, and verify the following on the cable (controller board will not be powered):

Pins Voltage

6, 17, 19 +24 V dc 1, 3-5, 11, 13, 15+5 V dc

If any of the voltages are incorrect, then replace the LVPS/HVPS. See “Dead machine

service check” on page 2-24.

Cooling fan service check

FRU Action

Cooling fan Make sure the fan cable plug is properly seated at J9 (controller board).

Turn the printer on. Within a few seconds, the controller board assembly should apply +24Vdc to pin2.

• If voltage is not present, then check or replace the controller board. See “Controller

board removal” on page 4-6.

• If voltage is present, then check pin 1 for 24 V dc as well. If it is close to 24 V dc while

the fan is still idle, then replace the fan. See “Fan removal” on page 4-16.

Cover interlock switch service check

Note: Make sure a print cartridge assembly is installed and the cover closes all the way, engaging the cover open switch lever.

FRU Action

Cover interlock switch Disconnect the cover interlock cable from the controller board at J7.

With the printer turned off:

1. Verify continuity between cable pin 1 and pin 2 with the door closed and discontinuity with the door open.

2. Verify continuity between cable pin 1 and pin 3 with the door open and discontinuity with the door closed.

3. Verify discontinuity between cable pins 2 and 3 whether the door is open or closed.

• If any fail, then replace the cover interlock switch.

• If both pass continuity, then turn the printer on, and measure +5 V dc on pin 2 at J7 on the controller board.

• Verify pin 3 at J7 is ground.

• If voltage or ground is not present, then see “Controller board service check” on

page 2-22 for more information.

Diagnostics information 2-23

Fuser service check

When toner is partially fused to the media, it is usually caused by low fuser temperature.

The line voltage to the printer must be within the following limits:

• 100 V ac-127 V ac for the 110 V model printer

• 200 V ac-240 V ac for the 220 V model printer

This printer uses a belt fuser and therefore does not have a lamp.

Fuser service check

FRU Action

Unplug the printer, and disconnect the fuser cable plug from the LVPS/HVPS board connector at CN102.

Check for continuity across the fuser by checking across the connector pins.

Fuser power cable LVPS/HVPS Fuser

Reconnect the cables, turn the printer on, and at &12, check for approximately +5 V dc on pin 1 and ground on pin 2. If line voltage is incorrect on pin 1, then see “Controller board

service check” on page 2-22 for more information.

• If there is continuity, then check the LVPS/HVPS. See “LVPS/HVPS service check”

on page 2-25.

• If there is no continuity, then disconnect the fuser power cable at both ends and check each conductor for continuity. Replace cable if necessary.

• If the cable tests good, then replace the fuser.

Disconnect the thermistor cable from J12 on the controller board. Measure the resistance across the ends of the thermistor cable. Replace the fuser assembly if the resistance is lower than 1K ohm or shorted. Note: Resistance measures approximately 400K ohms when cool and 1K ohms hot.

Fuser

LVPS/HVPS service check

FRU Action

LVPS portion of board

Fuses that open typically indicate a faulty LVPS/HVPS. Disconnect the power cable, and open the LVPS/HVPS enough to test the switch. The

switch will show continuity across the conductors with a meter when the switch is on. If the

LVPS/HVPS

switch is good, then see “Dead machine service check” on page 2-24 for more diagnostics.

If the buttons do not respond, then replace the operator panel. There is no test or repair for the faulty switches on the operator panel.

Paper feed service checks

Paper jam error indication during POST

FRU Action

Fuser (exit sensor) If the exit sensor flag, which is visible at the back of the fuser, is in any position other than

vertical, then the printer will display a paper jam. Make sure the flag is operating freely. Replace the fuser if the sensor is damaged.

Input/duplex sensor Manual feed sensor

Make sure the input paper feed sensors are working properly. A stuck or incorrectly installed sensor causes a paper jam indication.

Media picks but stops halfway through the printer

FRU Action

Input/duplex sensors (under print cartridge assembly) Input sensor (manual)

Make sure the input sensors are working properly. Check for a broken or stuck flag on the input sensors. Clear anything that keeps

the flags from rotating freely. Make sure the cables are seated on the controller board at J27 (input/duplex

sensor) and J23 (manual input). Check for +5 V dc on pin 2 and 5 at J27 (input/duplex sensors) and pin 2 at J23

(Input sensor). Voltages on pins 1 and 4 at J27 pin 1 at &23 should change as the flags intersect with the sensor.

• If correct, then replace the input paper feed sensor.

• If these voltages are not correct, then replace the controller board.

• Check the pick tires. Clean or replace as necessary.

Check tray for media catch points. If the sheet being fed stops momentarily, then the ACM applies additional vertical force,

causing additional sheets to feed. Do not mix media types in one tray.

Check the tires in the ACM assembly for signs of wear or damage. Replace the tires as necessary.

Open left cover, and observe the solenoid and clutch actions at the ACM and manual feed shafts as a print job is attempted.

Replace the faulty part.

Disconnect the solenoid cable at J26 on the controller board and measure the resistance across cable pins 1 and 2.

• The resistance should be approximately 70 ohms.

• If it is not, then replace the solenoid.

• If the resistance is approximately 70 ohms, then check the controller board. Pin 1 at

J26 should be +24 V dc. See “Controller board service check” on page 2-22 for more information.

Replace controller board as necessary.

Open the left cover, and verify that the solenoids and clutches are functioning when an attempt is made to feed the media.

Make sure the rubber tires on the ACM are installed and clean. Replace the tires, ACM drive, clutch assemblies, solenoids, or drive shaft as

necessary.

be too wide when the stack is short.

2-28

Media “trees,” wrinkles, stacks poorly, or curls

FRU Action

Fuser This problem is most likely due to a worn backup roll. It causes the printer to run hotter than

required for the media being printed. Excessive heat can cause media treeing problems, poor stacking, or curl.

Print the menu sheet found under Utilities. Look at the media settings. Some, such as card stock or rough texture, may require a

higher fuser temperature, which leads to more of these problems (except stacking) in plain paper.

• Change settings using the printer driver.

• Use the local printer setup utility (included on the CD) to change the NVRAM settings.

Try a different ream of paper. Moist media has a higher tendency to crease (treeing) and curl.

Parallel or USB port service check

1. Perform a print test to make sure the printer prints correctly. Verify that the indicator light is on, then print

the menu settings by selecting Print Menu under Utilities.

2. Be sure the printer parallel cable is designed for bidirectional printing.

3. Be sure the user’s application is set up correctly.

4. If the internal print test page prints correctly, the user’s application/printer driver is set up correctly, and the

correct bidirectional parallel cable is installed, but the printer still fails to print on command from the host computer, then replace the controller board.

5. Check the USB cable for continuity.

Diagnostics information 2-29

Print quality service checks

Note: Ensure the cover closes tightly. A gap in the opening may allow light to expose the photoconductor, resulting in a ‘dirty’ print. Extreme environmental conditions, temperatures, and humidity will affect the print quality.

Using print quality test pages

To help isolate print quality problems, like streaking, print test pages using the print quality test pages. To print the print quality test pages:

1. Enter Configuration Menu. a. Turn off the printer. b. Turn on the printer while pressing and holding and . c. Release the buttons when Performing Self Test displays. d. The message CONFIG MENU displays. e. Press to Prt Quality Pgs. f. Press to print the pages.

Four pages print to help evaluate print quality. The first page has various fonts and a graphic, the second page is gray with graphics, the third page is black, and the last page is blank.

2. Use the test pages to isolate problems such as light or toner streaks. See “POST symptom table” on

page 2-20 for solutions to these problems.

3. Press to Exit Config Menu and press .

To exit configuration, turn the printer off.

Note: Refer to the print defects guide at the end of the manual for repeating defects.

Printhead LVPS/HVPS Controller board

Remove the toner cartridge, and gently shake it to evenly distribute the toner. Check for cartridge damage.

Blank pages can be caused by a defective printhead assembly, LVPS/HVPS, or controller board.

• Printhead errors typically result in printer service errors unless there is blockage of the beam or dust on the lens. Check the lens and opening for blockage.

• Blank pages typically are caused by the PC roll not being properly charged. Try a different PC kit.

• With the cartridge out, check the spring loaded contacts on the right side for free motion. None should be ground except for #4 contact from the front.

Unplug the printer, and check the cable continuity between the LVPS/HVPS connector marked OPC (at CN202) and the corresponding wire form (spring) found about 14 mm above and to the right of the transfer roll gear.

• If there is not continuity, then call the next level of service.

Try a different toner cartridge and PC kit.

• If those fail, then replace the LVPS/HVPS, controller board, or the printhead in that order.

Also, see “Solving print quality problems” on page 2-34.

Banding appears as light or dark horizontal lines on a uniformly gray page or on a page with a large area of graphics. Banding is primarily due to a variation in the speed of the media as it feeds through the printer, especially in the developer and transfer process. It may also be a result of overly dry or moist environments.

With the printer off, check to make sure that the laser beam is not blocked. Inspect the toner cartridge and paper feed components, especially the drive coupler and

drive gears for debris, binds, or damage.

Toner on back of page

FRU Action

Configuration ID

The configuration ID is used to communicate characteristics of certain areas of the printer that cannot be determined by hardware sensors. The configuration ID was originally set when the printer was manufactured and is located on the printer label.

Edge to Edge

When Edge to Edge is set to On, text and graphics are printed with all margins set to the physical edges of the page. This feature does not work in PPDS emulation.

Par S Strobe Adj (parallel strobe adjustment)

This setting adjusts the factory setting for the amount of time the strobe is sampled to determine that valid data is available on the parallel port. Incrementing this value by one means the strobe is sampled 50 nanoseconds longer. The range of values are between -4 and +6, in increments of one. A value of zero indicates no change is made from the factory setting.

EP setup

EP Setup displays the following selections:

EP Defaults

Restores all EP settings to factory default values. Selections are Restore and Do Not Restore.

Fuser Temperature (Fuser Temp)

Changing this setting can reduce media curl or melting of some letterhead images. Selections are Normal (default), Lower, and Lowest.

• EP Defaults

• Fuser Temperature (Fuser Temp)

• Transfer

• Print Contrast

• Gap Adjust

• Automatic Darkness Adjustment (Auto Dark Adj)

Transfer

The transfer can be adjusted to Low, Medium, or High. The default setting is Medium.

Diagnostic aids 3-13

Print Contrast

The print contrast can be adjusted to Low, Medium, or High. The default setting is Medium.

Charge Roll

The charge roll can be adjusted to Low, Medium, or High. The default setting is Medium.

Gap Adjust

Adjusts the minimum gap between sheets during printing. This setting reduces speed (pages per minute), but can be used to reduce curl of printed media and improve stacking in the output bin.

The range is 0 (default) to 255. Adjusting by one results in 9 mm of increased gap.

Automatic Darkness Adjustment (Auto Dark Adj)

This setting attempts to optimize the amount of toner used when printing with a specific operating point. Each time this setting executes, the printer performs the following:

• Calibrates its toner density sensor

• Measures the reflectivity of its bare drum

• Prints patches on the drum and measures the drum’s reflectivity through the patches

• Cleans the transfer roll

• Calculates reflectivity ratios and operating points in order to attain each operating point’s

darkness target

• Modifies the EP mechanism as necessary to adjust toner darkness.

No messages are displayed on the operator panel to give any indication that this test is running. When deactivated, the printer disables.

Event log

Display Log

Selecting EVENT LOG provides a history of printer errors. The most recent error displays in position 1, and the oldest error displays in position 10 (if 10 errors have occurred). If an error occurs after the log is full, then the oldest error is discarded. Identical errors in consecutive positions in the log are entered. All 2xx and 9xx error messages are stored in the event log as well as the PC kit and maintenance counter resets and NVRAM resets initiated by the Factory Defaults setting in the UTILITIES menu.

Printhead assembly electronic adjustment

A step-by-step process to align a new printhead.

Note: Before aligning the printhead electronically, first align the printhead mechanically, if needed. See

“Printhead assembly mechanical adjustment” on page 3-17

1. Enter the Diagnostics menu. See “Entering Diagnostics menu” on page 3-5.

2. Press to enter the Registration menu.

3. Press to print the Quick test page.

(sample only; use actual sheet)

Quick Test page

3-16

4. In the Registration menu, select the right margin setting.

5. To determine the margin setting, choose the value that is closest to the darkest bar on the center graph of

the margin page. Add that value to the current right margin setting printed on the left hand side of the margin page. (The right margin setting will also appear on the operator panel display.) For example, if the right margin setting on the page is -2, and the number that is closest to the darkest line on the graph is 3 (-2+3), then the right margin setting will be equal to +1.

6. Press or to the desired setting, and press .

7. Print the Quick Test page again and check that the darkest line in the center graph is equal to zero. If it is,

then check to see if the left, top, and bottom margins are detected. If it is not, then repeat step 5.

Note: The alignment of the left margin positions the black plane to the right or left. The alignment of the right margin does not alter the margins and should only be used to adjust the printhead.

Printhead assembly mechanical adjustment

A printhead needs to be correctly positioned after it has been removed. Use a pencil to mark the screw locations of the old printhead on the metal frame. Align the new printhead relative to the location of the old printhead.

Note: Skew is caused by a sheet being fed through the printer while misaligned. The entire image is rotated relative to the sheet edges. However, a mechanically misaligned printhead causes the horizontal lines to appear skewed while the vertical lines remain parallel to the vertical edges.There are no adjustments for skew. Check the pick roll (paper pick assembly) for wear, the paper path for obstructions, the fuser for proper setting, and the tray paper guides for fit to the media.

Paper feed

skew

To adjust the printhead:

1. Enter the Diagnostics Menu. See “Entering Diagnostics menu” on page 3-5.

2. Select PRINT TESTS.

3. Select Tray 1.

4. Select Single.

5. Fold the printed test page on the left side so that a few millimeters of grid lines wrap around the outside of

the fold. See photo below.

6. Fold a second vertical fold near the center so that the left side top edge aligns with the right side top edge.

7. If the grid lines of the right flap align below the corresponding lines on the left flap, then adjust the printhead

clockwise relative to the printer and recheck. (See the left side of the figure below.) If the grid lines of the left flap align below the corresponding lines of the right side, then adjust the printhead counterclockwise. (See the right side of the figure below.)

8. After obtaining a properly adjusted image on the paper, tighten all three screws.

Note: The printhead must be aligned electronically. See “Printhead assembly electronic adjustment” on

page 3-16.

4. Repair information

Warning: Read the following before handling electronic parts.

Handling ESD-sensitive parts

Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usual precautions, such as turning off power before removing logic cards:

• Keep the ESD-sensitive part in its original shipping container (a special “ESD bag”) until the

part is ready to be installed into the printer.

• Make the least-possible body movements to prevent an increase of static electricity from

clothing fibers, carpets, and furniture.

• Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This

discharges any static electricity in your body to the printer.

• Hold the ESD-sensitive part by its edge connector shroud (cover); do not touch its pins. If a

pluggable module is being removed, then use the correct tool.

• Do not place the ESD-sensitive part on the MFP cover or on a metal table; if the ESD-

sensitive part needs to be put down for any reason, then first put it into its special bag.

• Machine covers and metal tables are electrical grounds. They increase the risk of damage

because they make a discharge path from your body through the ESD-sensitive part. (Large metal objects can be discharge paths without being grounded.)

• Prevent ESD-sensitive parts from being accidentally touched by other personnel. Install

machine covers when the machine is not being worked on, and do not put unprotected ESDsensitive parts on a table.

• If possible, keep all ESD-sensitive parts in a grounded metal cabinet (case).

• Be extra careful in working with ESD-sensitive parts when cold-weather heating is used,

because low humidity increases static electricity.

Repair information 4-1

Removal procedures

Note:

• Remove the toner cartridge and media tray before removing other printer parts. The toner cartridge should

be protected from light while out of the printer.

• We recommend disconnecting all external cables from the printer to prevent damage during service.

• Unless otherwise stated, reinstall the parts in reverse order of removal.

• When reinstalling a part held with several screws, start all screws before final tightening.

• Remove the paper tray and print cartridge before proceeding with a removal.
