Risk level

Low

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

Error code CE-09 on Sharp laser multifunction printers indicates that the scanned file exceeds the Maximum Size of E-mail attachments in the Web page or the mail server limit. Reduce scanned pages, lower resolution, change color mode, or adjust the Web page limit (1 MB to 10 MB or Unlimited).

Safety first

Stop and check this first

  • Sharp's manual notes that even if the scanned file size is within the Web page limit (factory default Unlimited, or 1 MB to 10 MB), the file will not be delivered to the recipient if it exceeds the limit set by the mail server administrator.

Safe checks you can perform

  • Reduce the number of original pages scanned into a single e-mail file
  • Lower the scanning resolution or change the color mode to make the file smaller
  • Check the 1 MB to 10 MB Web page attachment limit and the SMTP return address

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Configure Maximum Size of E-mail attachments in the machine Web page
  • Do not attempt this professional task: Inspect returned e-mail notices at the SMTP return address and administrator mailbox

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Configure Maximum Size of E-mail attachments in the machine Web page

    What they doReview the Maximum Size of E-mail attachments setting in the Web page (adjustable from 1 MB to 10 MB, with Unlimited as the factory default) and align it with the maximum attachment size permitted by the mail server.

    They must show youThe Maximum Size of E-mail attachments setting in the Web page and a successful Scan to E-mail test transmission.

    In writingThe configured Web page attachment limit in MB and the verified mail server transmission limit.

  2. Inspect returned e-mail notices at the SMTP return address and administrator mailbox

    What they doCheck the return address configured in the SMTP server and the designated administrator e-mail address for Undelivered Message notifications to confirm whether the mail server rejected the attachment size.

    They must show youThe SMTP return address configuration and confirmation that the recipient receives the scanned attachment.

    In writingThe mail server attachment limit findings and recommended scan resolution and page-count settings.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Reduce the number of original pages scanned into a single e-mail file

    No special tools

    Who:
    You, when loading originals in the document feeder or on the document glass.
    How:
    Decrease the amount of data sent in one e-mail transmission by reducing the number of original pages scanned into the file or splitting the job into smaller batches before resending.
    Result that matters:
    Each scanned file contains fewer pages and stays below the attachment size limit.
    If the smaller batch sends without showing CE-09:
    send the remaining pages in a separate e-mail transmission.
    If CE-09 still appears with only a few pages:
    lower the scanning resolution or change the color mode.
    Evidence to keep:
    Number of original pages per scan batch that transmits without triggering CE-09.

  2. Lower the scanning resolution or change the color mode to make the file smaller

    No special tools

    Who:
    You, in the scan settings on the Sharp operation panel.
    How:
    Change the scanning preferences before starting the scan: select a lower resolution, switch the color mode, or choose an appropriate original type such as Text instead of Photograph to make the scanned file size smaller.
    Result that matters:
    The resulting image file size is reduced so it fits within attachment limits.
    If the scan transmits without error CE-09:
    keep those resolution and color mode settings for multi-page jobs.
    If CE-09 continues even at lower resolution:
    check the attachment limit in the Web page and with your mail server administrator.
    Evidence to keep:
    Selected scan resolution and color mode settings that completed transmission.

  3. Check the 1 MB to 10 MB Web page attachment limit and the SMTP return address

    No special tools

    Who:
    You and the administrator of the machine Web page and mail server.
    How:
    Consult the administrator of the Web page to inspect the limit set in Maximum Size of E-mail attachments (the factory default setting is Unlimited, and a limit can be set from 1 MB to 10 MB), ask your mail server administrator for the single e-mail data limit, and check the return address configured in the SMTP server for any returned Undelivered Message e-mail.
    Result that matters:
    You verify both the Web page attachment cap and the mail server limit.
    If the Web page limit was set too low (such as 1 MB):
    the administrator can raise it up to 10 MB or Unlimited to match the mail server.
    If the issue persists after adjusting the file size and settings:
    turn the main power switch off, wait at least 10 seconds, turn it back on, or contact authorized brand service.
    Evidence to keep:
    Configured Maximum Size of E-mail attachments value and mail server data limit.

What it means

In the Sharp BP-20C25 and BP-10C20 Troubleshooting Guide (Indicators and Display Messages and Scan to E-mail sections), error code CE-09 means that the size of the scanned image file exceeds the limit set in Maximum Size of E-mail attachments in the Web page (where the factory default is Unlimited and a limit can be set from 1 MB to 10 MB) or exceeds the file size limit at the mail server. Other Sharp models may differ, and this code alone never proves a hardware component is faulty.

Warnings and stop conditions

  • Lowsource verified

    Sharp's manual notes that even if the scanned file size is within the Web page limit (factory default Unlimited, or 1 MB to 10 MB), the file will not be delivered to the recipient if it exceeds the limit set by the mail server administrator.

Symptoms and causes

Probable causes · in order

  • Scanned image file exceeds the Maximum Size of E-mail attachments setting in the Web pageCommon

    A file size limit between 1 MB and 10 MB has been configured in Maximum Size of E-mail attachments in the machine Web page, and the scanned document exceeds that threshold.

    Evidence: Sharp BP-20C25 / BP-10C20 Troubleshooting Guide - Indicators and Display Messages

  • Scanned data exceeds the single-transmission size limit enforced by the mail serverPossible

    Even when the file is within the machine Web page setting, the mail server administrator may restrict the maximum amount of data allowed in one e-mail transmission.

  • Large number of original pages or high-resolution color settings creating an oversized filePossible

    Scanning many pages into a single file or scanning a large area at high resolution in full color produces a large image file that exceeds attachment limits.
