Credit Handling on Sharp

Limitations and known issues

  • The print/copy operation may not stop immediately oncethe minimal balance has been reached. Depending on the device, there can be a small delay that allows users to overrun their balance by about four pages.

  • When the job is suspendeddue to insufficient funds, the following behavior differs depending on the supported OSA version.

    • OSA version < 4.0 It is not possible to print, copy or scan on the device, unless the suspended jobis manually deleted.

    • OSA version ≥ 4.0 Suspended scan and copyjobs are automatically deleted;Print jobs are stopped and wait for user input (retry/delete).

  • On OSA version < 4.0 If more jobs are printed in one batch, it might happen that the following jobs are suspended even though the user has enough credit.

    • The reason for this is thatthe quota calculation for the next job is donebefore the accounting information from the previous jobis sent.

    • The suspended jobs can be releasedon the "Limits" native screen. It is possible to select the suspended job there and re-check the limits. After confirmation,the job is released.

    • A user should not print multiple jobs in one print batch (print all, print multiple selected jobs) to avoid possible suspended jobs. Jobs should be printed one after another with a break of about five seconds between printing the next one to reduce the probability of suspended jobs.

Quota Calculation

  • After user authenticates on the terminal, the terminal checks whether the user has an account in the Payment System. If not, no restrictions are set for the user.

  • If the user has account in the Payment System, users quota are calculated based on users credit.

Devices with OSA 4.0 and higher

Print

The reservation amount for a print job is calculated from the parser data andthe maximum quota is used.

Copy and scan

  • Quotas are calculated according to the reserved amount.

  • The reserved amount depends on the user's current credit balance and the price for an A4 color page:

    • If the user's current credit is higher than the price for 100 A4 color pages, half of the user's current credit is reserved.

    • If the user's current credit is lower than the price for 100 A4 color pages but higher or equal to the price for 50 A4 color pages, the price for 50 A4 color pages is reserved.

    • If the user's credit is lower than the price for 50 A4 color pages, the user's entire credit is reserved.

  • Separate quotas are defined for color/black and white copies.

Devices with OSA lower than 4.0
