how to clear error code sc542 on Ricoh aficio 1515MF Lanier DSM415P

Hi Robert, I have searched by "error code p01-521" and got a number of hits. I suggest that you try the same and then make your own decisions on what sites offer the best chances of success.

I believe error code 521 refers to a low battery that requires replacing

it will automatically time out and you should just have to touch the screen for it to come back

If you're trying to get a case for Lumia 520 or 521, they're the same thing. The only difference between the 520 and 521 is carrier branding and radio support. Lumia 521 does GSM with HSPA+ (aka T-Mobile). If you're trying to get cases for them, the case will support both the 520 and 521.

Most common cause for this is sensors not positioned correctly. Make sure that the white arrow on the top sensor is aligned with the bottom sensor. See you user manual.

Also check that the senor used is the correct one for the maedia (i.e. black mark or transmissive).

I have an RP3105 with this error code. Next to the magnetic clamp that holds the master in place is another lever mechanism that lifts the master to present it to the waste master mechanism. This has a small white plastic wheel which is engaged to make it move. On my machine the wheel had broken in half. I superglued the two pieces together and everything works perfectly

The problem is clearly indicated on the error code.

"the server responded 521 user is over the limit for messages to be sent in a single day."

Have you been sending a lot of messages using that account? From yahoo:

The limit for messages for yahoo is 100 per hour, max 500 per day.

If you believe that you are the one not doing this, you can either report this to yahoo or checked your Yahoo! account immediately. Change the security settings and most specially the passwords. It could be that your account is used as a spam bot.
