HP CM8060/CM8050 Color MFP with Edgeline Technology - Fax problems

Before you can use the fax feature, you must set the date, time, location, and fax header information. This is a legal requirement in the U.S. and many other countries/regions.
Use the information in the following sections to resolve fax problems.

Fax checklist

  1. Make sure you are using the phone cord that came with the fax accessory. The analog phone cord that came with the fax accessory meets RJ11 specifications. The fax accessory requires an analog phone cord and an analog phone line.
  2. Make sure the phone jack is seated correctly in the fax connector on the device.
  3. Make sure the phone line is working correctly. Attach a phone to the wall jack and verify that you can hear a dial tone and you can make a phone call.
  4. Make sure you are using an analog phone system. Some business phone systems are digital and are not compatible with the fax accessory. The device cannot send or receive faxes if it is connected to a voice-over-Internet (VoIP) phone system.
  5. Make sure the fax accessory is connected to the first incoming phone line. HP recommends against using a roll-over phone line in which incoming calls are sent to the next available phone line.
  6. Make sure you are not using a parallel or “T” phone-line splitter. These splitters can degrade the phone signal.
  7. If you are using a surge-protector between the fax accessory and the wall jack, it could be causing communication problems. Try connecting the fax accessory directly to the phone jack on the wall.
  8. If you are using a voice-messaging service or an answering machine, make sure the “rings to answer” setting for the messaging service or answering machine is higher than the “rings to answer” setting for the fax accessory.
  9. Print the configuration pages to verify that the fax accessory is correctly installed and is functioning correctly. If the configuration pages do not include a fax accessory page, then the fax accessory is not installed correctly. If the fax accessory page prints, look under the Hardware Information for the Modem Status section.
    • Operational/Enabled: The fax accessory is installed and ready.
    • Operational/Disabled: The fax accessory is installed, but the Fax feature is disabled. Enable the fax feature by using the Fax tab in the embedded Web server. Select Fax Send Setup. See Fax send setup.
    • Non-operational: The fax firmware has a problem, and it needs to be updated. Contact the HP-authorized support person.
    • Damaged: The fax accessory is damaged. Contact the HP-authorized support person.

General fax problems

General fax problems
Issue
Cause
Solution
A fax was sent after pressing the Stop button on the control panel.
Pressing the Stop button does not cancel faxes that have been completely scanned and are in the job queue.
To cancel a fax that is waiting in the job queue, open the Job Status feature on the control panel. See Cancel faxes.
The same billing code is being used for all outgoing faxes.
The default billing code is being used for all faxes.
If you want to use different billing codes for different fax jobs, set the Billing Codes setting to Billing codes on.For each fax job, a prompt appears so that you can enter a billing code that is different than the default billing code. See Fax Setup menu.
The Fax feature does not appear on the Home screen, or it is unavailable, even though you have enabled the feature.
If you are using the analog fax accessory, it might not be connected correctly, or it might be malfunctioning.
Contact the HP-authorized support person.
If you are using a LAN Fax service or an Internet Fax service, the device might be configured to use an internal modem instead.
Make sure the fax send method is not set to Internal Modem. See Fax Setup menu.

The phone line might not be working.
Attach a phone to the wall jack and verify that you can hear a dial tone and you can make a phone call.
An answering machine might be interfering with the incoming fax.

The Dialing Mode setting might not match the required setting for your telephone service provider.
Make sure the Dialing Mode setting is correct. See Fax Setup menu.
If an error occurs during fax transmission, part or all of the data might be lost.
Enable the Error Correction Mode feature so that the device sends the error portion again.
The Fax V.34 feature might be sending faxes at a speed that is too high for current phone line conditions.
Temporarily disable this feature to see if you can send the fax. See Troubleshooting menu.
The fax is being sent, but very slowly.
The resolution for scanning the original document might be too high.
When scanning the original document, touch More Options and then touch Resolution. Set the resolution to a lower level to increase the fax transmission speed.
