Description

Recommended action

232 233 234

235 (ECM

error) 236

(ECM error)

237

A communication failure has

occurred between the two machines.

-Or-

The user at the remote machine

might have pressed

CANCEL

-Or-

The power at the remote machine

has been interrupted or deliberately

turned off, causing the fax session to

be interrupted.

Attempt to receive the fax again after

telephone-line conditions have

improved.

If the error persists, and error correction

is in use for the fax session, disable the

ECM.

238 239 (ECM

error) 240

(ECM error)

241 (ECM

error)

The remote fax machine sent an

unexpected communication.

None. This is a defect in the remote sending

machine.

242

The remote fax machine is

attempting to receive instead of

send. Both machines have attempted

to start receiving at the same time.

It is possible to accidentally initiate a

fax reception after dialing on many

machines, if there is no paper in the

machine, or if the paper is not

correctly loaded and cannot be

sensed by the appropriate document

sensor.

Ensure that a document is ready and is

correctly loaded in the transmitting fax

machine and that the remote machine is

attempting to transmit and not to receive.

243 244

The user of the remote machine has

pressed the Stop button on that

machine, which caused the session

to be prematurely terminated.

-Or-

The remote fax machine identified a

feature incompatibility between the

two machines and has terminated

the session. For example, the

product tried to initiate polling, but the

remote machine did not support this

mode of operation.

Confirm that the remote user is not

inadvertently attempting a poll

transmission from the product, instead of

transmitting to the product. This mode of

operation must be specially configured

on the product. If poll transmission from

the product is the appropriate mode of

operation, confirm that the product has

been configured for this operation.

Reconfigure the local fax machine to use

different configuration settings, change

the ECM setting to the opposite of the

current setting, or select a slower

reception speed.
