HP LaserJet Enterprise Flow MFP M525 - User Guide

Problem Cause Solution
The product is either low on toner or has run
out of toner.
If congured, the product stops printing as
soon as it is low on toner or runs out of
toner. Any faxes received are stored in
memory and print after the toner has been
replaced.
The incoming call might be a voice call. Incoming voice calls usually show up in the
call report as a No Fax Detected error.
Because these are voice calls and not a fax
error, no action is necessary.
The incoming fax was interrupted. Verify that the fax telephone line does not
have an activated call-waiting feature. A
call-waiting notice can interrupt a fax call in
progress, which causes a communication
error.
The Fax Printing Schedule feature is set to
the Always store faxes option.
Change the Fax Printing Schedule setting to
the Always print faxes option.
Problems with sending faxes
Problem Cause Solution
Faxes are transmitting very slowly. You might be sending a complex fax, such
as one with many graphics.
Complex faxes take longer to transmit.
The receiving fax machine might have a
slow modem speed.
The fax accessory only sends the fax at the
fastest modem speed the receiving fax
machine can use. Wait for the fax
transmission to complete.
The resolution at which the fax was sent or
is being received is very high. A higher
resolution typically results in better quality,
but also requires a longer transmission
time.
Decrease the resolution and change the
Optimize Text/Picture option.
If there is a poor phone-line connection, the
fax accessory and the receiving fax machine
slow down the transmission to adjust for
errors.
Cancel and resend the fax. Ask the phone
company to check the phone line.
The document might have a gray
background, which can increase fax
transmission time.
Use the Image Adjustment feature to clean
up the background shading.
Faxes quit during sending. The receiving fax machine might be
malfunctioning.
Try sending to another fax machine.
The phone line might not be working. Disconnect the fax accessory from the
phone jack, and connect a phone. Try to
make a phone call to ensure the phone line
is working.
The phone line might be noisy or poor
quality.
Try using a slower fax speed to improve the
reliability of transmission. Use the Fax
Dialing Settings menu to set the fax speed
for sending faxes.
