   I have a Panasonic KXP-4450 and it complains about not having any
toner.  Let me explain.  When you turn on the printer it displayes 'WARM
UP' and after it completes this phase it displays the errOr 'TONER
CHARGING U22' at which time you can here the printer purr while the
developer toner roller cycles.  This goes on for about a minute and a
half when finally the printer stops and displays 'CALL SERVICE E13'   I
have checked the toner tank and even added a little toner (it was
already full).  The master unit is in excellent condition and the
printer is in over all good condition particularly since it is so old.
I looked and found a sensor that must detect the toner/ferrous
concentration on the bottom of the developer and I am guessing that it
must not be detecting proper toner concentrations.  Can anyone give me
some suggestions?  I think that this might be something simple.  I have
already checked and cleaned all electrical contacts and interior parts
but no avail...  Thanks for any help.
