What This Guide Helps With

This guide helps troubleshoot the error “Printing is disabled with one battery only, please check the battery” on the Philips PageWriter TC70 electrocardiograph. This condition can prevent ECG reports from printing when the cardiograph detects that only one battery is installed, available, or properly recognized.

The device may still power on, but printed ECG output may be disabled until the battery configuration is corrected.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• If the PageWriter TC70 is needed for active patient testing and printing is unavailable, use another verified ECG machine or follow an approved alternate ECG documentation workflow.
• Do not continue relying on the affected cardiograph for printed ECG output until the battery condition is corrected.
• Expected outcome: Patient care is not delayed by a cardiograph that cannot print.

Verify the Reported Error and Behavior

• Power on the Philips PageWriter TC70 and confirm the exact message: “Printing is disabled with one battery only, please check the battery.”
• Check whether the issue occurs at startup, when attempting to print an ECG, while operating on battery power, or after battery replacement or battery removal.
• Confirm that printing is actually disabled and that the complaint is not related to paper loading, print quality, or printer door status.
• Expected outcome: The battery-related printing error is confirmed before printer troubleshooting begins.

Translate the Error Into the Real-World Condition

• This error means the cardiograph detects that only one battery is installed or available.
• The PageWriter TC70 requires both batteries installed for battery-supported printing.
• With only one battery detected, the unit may still power on, but printing may be disabled.
• Expected outcome: Troubleshooting stays focused on battery presence, battery seating, battery charge, and battery detection before assuming a printer failure.

Connect the Cardiograph to AC Power

• Plug the TC70 directly into a known-good AC outlet.
• Avoid loose outlets, extension cords, or power strips during troubleshooting.
• Confirm the AC power indicator is present and the device powers normally.
• Expected outcome: The cardiograph remains powered from AC while the battery condition is checked.

Check That Both Battery Bays Are Populated

• Inspect the battery compartment and verify that two approved batteries are installed.
• If only one battery is installed, insert the second compatible battery.
• Confirm both battery positions are occupied and each battery is properly latched.
• If installing the second battery clears the message and printing returns, perform a controlled test print before returning the device to service.
• Expected outcome: Both battery bays are populated and the one-battery condition is corrected.

Reseat Both Batteries

• Power the unit down if appropriate.
• Remove and reinstall both batteries, making sure each battery is fully seated and latched.
• Check for loose fit, partial insertion, bent contacts, debris, or obvious damage around the battery area.
• Expected outcome: Both batteries sit securely and are detected by the cardiograph.

Check Battery Condition and Charge Status

• With the unit connected to AC power, allow the batteries to charge if either battery appears depleted.
• Review the battery status information on the cardiograph if available.
• Look for signs of a failed battery, such as a battery not recognized, not charging, showing abnormal status, or causing the unit to detect only one battery after reseating.
• Do not use batteries with cracked, swollen, leaking, or physically damaged housings.
• Expected outcome: Both batteries are recognized and able to support normal operation.

Swap With Known-Good Batteries if Available

• If the error remains, install a known-good compatible battery set if facility policy allows.
• Recheck for the error and attempt a test print.
• If the message clears with known-good batteries, the original battery or battery set is the likely cause.
• If the message remains with known-good batteries, the issue is likely device-side battery detection, battery interface, or internal connection related.
• Expected outcome: Battery failure is separated from a possible device-side detection fault.

Check for Printer Function After Battery Correction

• Once both batteries are installed and detected, attempt a controlled test print.
• Confirm the error does not return.
• Confirm printing is no longer disabled.
• Confirm paper feeds normally and print quality is acceptable.
• Check that no additional printer or battery warnings appear.
• Expected outcome: The cardiograph prints normally after the second battery is installed and recognized.

Stop When Resolved

• If inserting, charging, or reseating the second battery clears the error and the TC70 prints normally, document the correction and return the device to service.
• Expected outcome: The device is safe for normal ECG acquisition and printing.

If the Problem Persists

If both batteries are installed, seated correctly, charged or replaced with known-good batteries, and the same error remains, external and common causes have been ruled out.

A persistent one-battery detection error may indicate a battery contact issue, battery interface problem, internal connection issue, or battery detection circuitry fault.

Remove the cardiograph from service, label it Out of Service, and send it for repair or bench evaluation.

Knowing when to stop is proper troubleshooting.

Clinical Use Tip

Never troubleshoot battery or printing problems while the PageWriter TC70 is actively being used for patient ECG testing. Move the patient to a backup ECG machine first if printed output is required and the cardiograph has an unresolved battery-related printing error.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Philips PageWriter TC70 displays error 'Printing is disabled with one battery only, please check the battery.' Staff reports ECG printing is disabled."

Cause

What was observed during troubleshooting.

Example:
"Only one battery was installed in the cardiograph, preventing battery-supported printing."

Resolution

What action was taken.

Example:
"Installed second approved battery, verified both batteries were seated, connected unit to AC power, cleared error, and completed successful test print. Device returned to service."

Helpful Details to Include (If Known)

• Alarm behavior
• Accessories swapped
• Power behavior
• Environmental factors
• Indicator lights
• Final device status

Final Thought

Battery-related printing errors should be approached logically. Confirm the message, verify both batteries are installed and detected, rule out simple seating or charge issues, and escalate when the device still cannot recognize a complete battery set. Clear documentation protects patient care and supports proper repair decisions.

That is successful troubleshooting.
