What This Guide Helps With
Troubleshooting printer, paper feed, blank printout, jam, or report output problems on the ARKRAY AUTION ELEVEN AE-4022.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Confirm the AUTION ELEVEN AE-4022 is not actively processing a patient urine strip before opening the printer area, replacing paper, or restarting the analyzer.
If patient testing is urgent, have laboratory staff use another validated analyzer or follow the facility’s approved downtime documentation process.
Expected outcome: Patient testing and result reporting are not compromised during troubleshooting.
Verify the Reported Printer Problem
Ask staff what they observed.
Confirm whether the issue is:
- No printout after testing
- Paper not feeding
- Paper jam
- Blank printout
- Faded or incomplete report
- Printer noise with no paper movement
- Results visible on screen but not printed
- Printing failure after paper replacement
Expected outcome: The issue is confirmed as a printer or paper feed problem, not a testing, LIS, operator workflow, or result storage issue.
Confirm Results Are Still Available
Check whether the urine result is still visible on the analyzer display or stored in memory.
If the result is needed for patient care, have laboratory staff document or transmit it according to lab policy before further troubleshooting.
Expected outcome: No completed patient result is lost due to printer troubleshooting.
Check Printer Paper Supply
Open the printer cover and verify that paper is installed.
Confirm the roll is not empty, crushed, wet, contaminated, or installed loosely.
Replace the paper roll if it is low, damaged, or questionable.
Expected outcome: The printer has usable paper available for feeding and printing.
Verify Paper Orientation
Confirm the thermal paper is loaded in the correct direction.
Thermal printers only print on the coated side of the paper. If the paper is reversed, the analyzer may feed paper but produce a blank report.
Expected outcome: Paper feeds with the printable thermal side correctly positioned.
Check for Paper Jam or Torn Paper
Inspect the paper path for torn paper, small scraps, folded edges, or debris.
Remove only accessible paper fragments without forcing the printer mechanism.
Do not use sharp tools that could damage the print head, roller, or paper sensor area.
Expected outcome: The paper path is clear and the paper can advance normally.
Reload the Paper Roll Cleanly
Remove the paper roll and reload it neatly.
Make sure the paper edge is straight and not curled, folded, or jammed under the cover.
Close the printer cover fully.
Expected outcome: The printer cover seats properly and the paper is positioned for normal feeding.
Check for Cover or Door Not Fully Closed
Confirm the printer cover is latched correctly.
A loose or partially closed cover can prevent proper paper pressure against the print mechanism.
Expected outcome: The printer cover is secure and paper feed pressure is restored.
Perform a Controlled Print Test
Use an available analyzer print function, stored result print, or approved test report workflow if accessible.
Do not use active patient testing just to test the printer.
Expected outcome: The analyzer prints a readable report without paper slipping, jamming, or feeding incorrectly.
Check Print Quality
If the report prints but is faint, incomplete, or uneven, replace the paper roll with a known good thermal roll approved for the analyzer.
Avoid using old, heat-exposed, damp, or non-thermal paper.
Expected outcome: Print quality improves with known good paper.
Check for External Contamination
Inspect around the printer opening for urine residue, control material, dust, or paper debris.
Clean only external and user-accessible surfaces according to facility-approved cleaning practices.
Do not spray cleaner directly into the printer.
Expected outcome: External contamination is not interfering with paper movement or report readability.
Verify Printer Settings or Output Selection
Check whether printing has been disabled, set to manual print, or redirected through another result reporting workflow.
Confirm with lab staff whether the analyzer is expected to print automatically after each test.
Expected outcome: The printer behavior matches the laboratory’s intended workflow.
Power Cycle the Analyzer Safely
If the paper path is clear and paper is correctly loaded, restart the analyzer when it is safe to do so.
Allow the analyzer to complete startup before attempting another print test.
Expected outcome: Temporary printer or software lockups clear after restart.
Check for Repeated Jam or Feed Failure
If the same jam, slipping, or no-feed condition returns with known good paper and correct loading, suspect a printer roller, paper sensor, cover latch, motor, or internal printer assembly issue.
Do not disassemble the printer mechanism beyond normal paper access.
Expected outcome: Internal printer failure is suspected only after external causes are ruled out.
Return to Service Only After Successful Verification
If the printer feeds correctly and produces a readable report, document the action and return the analyzer to service.
If printing is required for the lab’s workflow, do not return the analyzer to normal use until report output is verified.
Expected outcome: The AUTION ELEVEN AE-4022 is returned to service only when result documentation is reliable.
If the Problem Persists
If the printer still does not feed paper, repeatedly jams, produces blank output with correctly loaded thermal paper, or fails to print after basic checks, common external causes have been ruled out.
Remove the AUTION ELEVEN AE-4022 from service, label it Out of Service, and send it for repair or bench evaluation. The issue may involve the internal printer assembly, paper sensor, thermal print head, cover switch, wiring, or control circuitry.
Knowing when to stop is proper troubleshooting. Do not continue using a urine analyzer if required result documentation cannot be verified.
Clinical Use Tip
Do not troubleshoot the printer while the analyzer is actively processing patient specimens. If printed reports are required and the printer is unreliable, move testing to another validated analyzer or use the laboratory’s approved downtime process before continuing patient testing.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Laboratory staff reported that the ARKRAY AUTION ELEVEN AE-4022 was not printing urine analyzer reports after testing."
Cause
What was observed during troubleshooting.
Example:
"Printer paper was installed backward, causing the analyzer to feed paper but produce blank printouts."
Resolution
What action was taken.
Example:
"Reloaded thermal paper in the correct orientation, verified readable test print, confirmed stored result printout, and returned analyzer to service."
Helpful Details to Include (If Known)
- Whether results were visible on the analyzer display
- Whether results were stored, printed, or transmitted
- Paper roll condition
- Paper orientation verified
- Printer cover closed and latched
- Any jammed or torn paper removed
- Whether known good thermal paper was tested
- Print quality observed
- Any printer noise during feed attempt
- Whether the issue returned after restart
- Environmental factors around the printer area such as moisture, dust, urine residue, control material, or paper debris
- Indicator lights, screen messages, or printer prompts observed
- Final device status
Final Thought
Printer issues on the AUTION ELEVEN AE-4022 should be approached like result documentation problems, not just paper problems. Protect patient results first, check the simple external causes, verify print output, and escalate when the printer mechanism appears unreliable. Good CCR documentation makes the repair history clear and supports safe analyzer use.
That is successful troubleshooting.
