TEC test procedure — Printers, digital duplicators and MFDs with print capability, and fax machines
| Notes: | ||||
| — Before beginning the test, it is helpful to check the power-management default delay times to ensure they are as-shipped, and to confirm that there is plenty of paper in the device. | ||||
| — The ‘Zero meter’ instruction may be carried out by recording the accumulated energy consumption at that time rather than literally zeroing the meter. | ||||
| — Step 1 — The off measurement period can be longer if desired, to reduce measurement error. Note that the off power is not used in the calculations. | ||||
| — Step 2 — If the unit has no ready indicator, use the time at which the power consumption level stabilises to the ready level. | ||||
| — Step 3 — After recording the Active0 time, the remainder of this job can be cancelled. | ||||
| — Step 5 — The period of 15 minutes is from job initiation. The unit must show increased energy consumption within five seconds of zeroing the meter and timer; it may be necessary to initiate printing before zeroing to assure this. | ||||
| — Step 6 — A unit that is shipped with short default delay times might begin steps 6-8 from sleep. | ||||
| — Step 9 — Units may have multiple sleep modes so that all but the last sleep mode are included in the final period. | ||||
| Step | Initial state | Action | Record (at end of step) | Possible states measured |
|---|---|---|---|---|
| 1 | Off | Plug the unit into meter. Zero the meter; wait test period (five minutes or more). | Off energy | Off |
| Testing interval time | ||||
| 2 | Off | Turn on unit. Wait until unit indicates it is in ready mode. | — | — |
| 3 | Ready | Print a job of at least one output image but no more than a single job per job table. Record time to first sheet exiting unit. Wait until the meter shows that the unit has entered its final sleep mode. | Active0 time | — |
| 4 | Sleep | Zero meter; wait one hour. | Sleep energy | Sleep |
| 5 | Sleep | Zero meter and timer. Print one job per job table. Record time to first sheet exiting unit. Wait until timer shows that 15 minutes have elapsed. | Job1 energy | Recovery, active, ready, sleep |
| Active1 time | ||||
| 6 | Ready | Repeat step 5. | Job2 energy | Same as above |
| Active2 time | ||||
| 7 | Ready | Repeat step 5 (without active time measurement). | Job3 energy | Same as above |
| 8 | Ready | Repeat step 5 (without active time measurement). | Job4 energy | Same as above |
| 9 | Ready | Zero meter and timer. Wait until meter and/or unit shows that unit has entered its final sleep mode. | Final time | Ready, sleep |
| Final energy | — | |||
Each image is to be sent separately; they may all be part of the same document, but should not be specified in the document as multiple copies of a single original image (unless the product is a digital duplicator, as specified in Section D.2(b)).
For fax machines that only use one image per job, the page is to be fed into the unit’s document feeder for convenience copying, and may be placed in the document feeder before the test begins. The unit need not be connected to a telephone line unless the telephone line is necessary for performing the test. For example, if the fax machine lacks convenience copying capability, then the job performed in step 2 should be sent via phone line. On fax machines without a document feeder, the page should be placed on the platen.
