BATTERY REPLACEMENT
You can use a battery pack as a source of power. The battery pack that comes with your notebook is not fully charged at the time of purchase. Follow the steps below to insert and charge the battery pack.
To Insert the Battery Pack
You can insert or remove the battery pack without turning off the notebook when your notebook is connected to the AC adapter. Before inserting or removing a battery pack, close the cover.

  • Move the lock lever on the bottom of the notebook to the UNLOCK position.
  • Align the grooves and tabs on the battery with the tabs and notches on the back of the notebook, and then slide the battery toward the notebook until it clicks into place.
INSERTING BATTERY PACK
Slide the lock lever into the LOCK position to secure the battery on the notebook.

The notebook automatically charges the battery (the battery indicator light flashes in a double-blink pattern as the battery charges). When the battery is 85% full, the battery indicator light turns off. This process takes 5.5 hours if the system is on. To charge the battery completely, continue charging for approximately 3 additional hours.
To Remove the Battery Pack
You can insert or remove the battery pack without turning off the notebook when your notebook is connected to the AC adapter. Before inserting or removing a battery pack, close the cover.
  • Turn off the notebook and close the cover.
  • Slide the lock lever to the UNLOCK position.
  • Slide the release lever to the UNLOCK position and slide the battery away from the notebook.

You may lose data if you remove the battery pack while the notebook is on and not connected to the AC adapter or if you remove the battery while the notebook is in a power saving mode.
  • If you find that an application exhibits unexpected behavior (such as reduced video quality) after returning from a power saving mode, you should close that application before your notebook enters a power saving mode.
  • For maximum audio and video performance, use Power Panel to select either the AC Power Profile or the Power Management Off profile.
  • If your battery level falls to less than 10 percent, you should either attach the AC adapter to recharge the battery or shut down your notebook and insert a fully charged battery.

When the internal backup battery is low on power, it may not be able to boot your system properly. You can correct this condition as follows:
  • Plug in the AC adapter and allow the notebook to charge for one hour while the power is on. Do not use the notebook during this time.
  • After one hour, turn the power off and then on again. To charge the internal backup battery fully, keep the AC adapter connected for more than 24 hours after turning the power on. You can use your notebook while charging the battery.

The operating system may become unstable if a lower power state such as Hibernate is initiated and then changed before the operating system completely enters the lower power state. To restore the notebook to its normal operating stability, close all open applications, and slide the power switch forward and hold it there for four seconds or more to completely shut down the notebook.

MECHANISM
Document feed block
Document feed operation
  • The original, which is set in the document hopper, feeds automatically when the front sensor is activated. This in turn activates the pulse motor which drives the document supply roller. The document stops when the lead edge is detected by the document sensor.
  • The lead edge of the original is fed a specified number of pulses after the lead edge of the document is detected for the reading process to begin.
  • The trailing edge of the original is fed a specific number of pulses after the trailing edge of the document deactivates the document sensor. The read process then stops and the original is discharged.
  • When the front sensor is in the OFF state (any document is not set up in the hopper guide), the drive will be stopped when the document is discharged.
Hopper mechanism

The hopper section contains document guides that are used to adjust the hopper to the width of the original document. This ensures that the
original feeds straight into the fax machine for scanning.
Document width: 148 mm to 216 mm (A5 longitudinal size to Letter longitudinal size)
NOTE: Adjust the document guide after setting up the document.
Automatic document feed
  • Use of the paper feed roller and separation rubber plate ensures error-free transport and separation of documents. The plate spring presses the document to the paper feed roller to assure smooth feeding of the document.
  • Document separation method: Separation rubber plate.

NOTE: Double-side coated documents and documents on facsimile recording paper should be inserted manually. The document feed quantity may be changed according to the document thickness.
Documents corresponding to a paper weight heavier than 64.3kg (74.3g/m2) and lighter than 135kg (157g/m2 ) are acceptable for manual feed.
Documents heavier than 135kg in terms of the paper weight must be duplicated on a copier to make it operative in the facsimile.
Loading the documents
  • Make sure that the documents are of suitable size and thickness, and free from creases, folds, curls, wet glue, wet ink, clips, staples and pins.
  • Place documents face down in the hopper.
  • Adjust the document guides to the document size.
  • Align the top edge of documents and gently place them into the hopper. The first page under the stack will be taken up by the feed roller to get ready for transmission.

NOTES:
Curled edge of documents, if any, must be straighten out.
Do not load the documents of different sizes and/or thickness together.
  • Documents requiring use of document carrier
  • Documents smaller than B6 (128mm x 182mm).
  • Documents thinner than the thickness of 0.06mm.
  • Documents containing creases, folds, or curls, especially those whose surface is curled (maximum allowable curl is 5mm).
  • Documents containing tears.
  • Carbon-backed documents. (Insert a white sheet of paper between the carbon back and the document carrier to avoid transfer of carbon to the carrier.)
  • Documents containing an easily separable writing material (e.g., those written with a lead pencil).
  • Transparent documents.
  • Folded or glued documents.  Document in document carrier should be inserted manually into the feeder.
Recording block

Driving
In the drive mechanism, the rotating force of the pulse motor for both transmission and reception is transmitted to the paper supply roller, the recording paper feed roller and imaging film drive gear through the pulse motor axle gear, reduction gear and planetary gear.
Recording
This equipment employs the thermal transcription system, which used the thermal head imaging film.
Thermal head:  The thermal head is composed of 2,016 heating elements in traverse line, and the resolution power is 8 dots/mm. The maximum speed is 10ms/line.
Structure of recording mechanism
Recording is achieved by applying a suitable pressure to the thermal head through the imaging film of the recording paper feed roller and the recording paper.  The main scanning is electronically done, and the sub-scanning is mechanically done (by sending the recording paper with the recording paper feed roller).
Recording paper transfer sequence
The recording paper stored in the RP hopper is fed with the PU roller, and the recording paper is stopped when the P-IN sensor is turned on by sensing its lead edge.
Hereafter, the imaging film and recording paper are transferred with the recording paper feed roller, and thermal transcription is done on the recording paper.
After thermal transcription, the imaging film is taken up by the roller on the take-up side, and the recording paper is discharged by the PO roller.  As basic, the density unevenness mainly results from the longitudinal misalignment of the thermal head to the heater line. Otherwise, the head is in uneven contact with the recording paper feed roller, or the imaging film is wrinkled.
The following items are described as the simplified checking method.
  • Is the power and signal cables of the thermal head suitably treated?
  • Does the same symptom appear even if the thermal head pres-sure spring is replaced?
  • Is the feed roller of the recording paper concentric? (Density is uneven at intervals.)
  • Does the same symptom appear even if the thermal head is replaced?
  • Is the imaging film stained or wrinkled?

  • To change the parameter number use channel up and down buttons.
  • To adjust the current value of that parameter use volume +and - buttons.
  • To access and change any of the adjustments, the proper parameter pass number must be entered.  
  • When these parameters are modified, the T-Chip and the corresponding EEPROM are updated. All service adjustments are bus controlled, except focus and screen.
NOTE: In order to adjust the RF AGC, audio or video levels, tuner, PIP, or stereo circuits, the Chipper Check hardware and software must be used. This can be purchased from Thomson Electronics. Before making any changes to any of the values, record the On Set values.
ADJUSTMENT PARAMETERS
ERROR CODES
  • If certain failures occur, the matching error codes will be stored in the EEPROM. These error codes will be displayed in parameters 1, 2, and 3. 
  • The first failure error code will be stored at parameter 1 and the second failure error code will be stored at parameter 2. 
  • Parameter 3 will be updated to display the most recent failure occurred in the chassis. If a failure of a bus IC occurred, the normal acknowledgment checking of that bus will be disabled in the service mode and the address of that IC which failed will be stored in one of the error code parameters. 
  • After every repair is done to the chassis it is recommended to check the error code parameters, and reset them back to value 0.
