富士通G06F公報の請求の範囲から作成した4037文対の訓練データと504文対からなる評価用対訳を用いて、NICT特許NTをベースエンジンとするアダプテーション＋EBMTの訓練データを繰り返した文対による効果検証の実験を行った。以下の結果が得られた。
①英日・日英とも繰り返し３でスコアが２から3ポイント向上し、日英で顕著なベースNMTの訳抜けはアダプテーション＋EBMTエンジンでは半減する。
②アダプテーション＋EBMTエンジンの欠点として、日英では過翻訳が英日翻訳より出やすい。
③対策：訓練用文対はあらかじめアライメントツールでフィルタリングを行い、訓練データを繰り返した文対（3程度で十分）で訓練する＋追加の後処理で改善できることが確認された。（過翻訳件数117件⇒6件まで減少）NICTアダプテーション＋EBMTエンジンの実力とそれを用いた統合翻訳環境

FIG. 1 illustrates a schematic configuration of a main part of a control system of the image forming system according to
the present example embodiment of the present invention.
FIG. 7 is an explanatory view illustrating a display example of a sheet output setting screen of the buffer sheet according
89.4
to the one embodiment of the present disclosure.
For example, the image processor 30 performs tone correction on the basis of tone correction data (tone correction table)
64.2
under the control of the controller 100.
However, in a case where printing at a low printing rate (a ratio of the number of print pixels to the total number of pixels
in one page) continues, only a small amount of toner is consumed.

Wherein the adjustment member is disposed at an outlet of the air passage, and the adjustment member causes air
47.8flowing in the air passage to branch into a direction of the transport path and a direction of the developing unit andadjusts an amount of air flowing in each direction.
The peripheral surface of the 5D of each photoconductor drum is uniformly and positively charged by the corresponding
69.0
charger 5F, and then exposed by the laser scanning unit 5S.

FIG. 2 is a diagram illustrating a main part of an entire control system provided in the image forming system
according to the present embodiment.
FIG. 7 is an explanatory diagram illustrating a display example of a buffer sheet discharge setting screen according
56.4
to an embodiment of the present invention.
For example, the image processing section 30 applies tone correction on the basis of tone correction data (a tone
80.4
correction table) under the control of the controller 100.
However, only a small amount of toner is consumed in a situation in which printing is repeatedly performed with alow coverage ratio (ratio of printed pixels relative to the total number of pixels in one page).

Next, each primary transfer roller 64 transfers the developer image onto an outer circumferential surface of theintermediate transfer belt 63 from the circumferential surface of the corresponding photosensitive drum 41.

Note that according to the present embodiment, the printer 220 is described as a tandem-type color printer, but
the printer 220 may be a color printer of another type or a monochrome printer. Note that according to the present
embodiment, the printer 220 is described as a tandem-type color printer, but the printer 220 may be a color printerof another type or a monochrome printer.
Note that until the controller 100 receives a print instruction, the controller 100 continues the toner-supply
62.8
suspension, that is, the developing roller 54 is kept separated from the photosensitive drum 51.
Similarly, the bearing holder 6b of the primary transfer roller 38b is supported by the second step rib 51, the74.6bearing holder 6c of the primary transfer roller 38c is supported by the third step rib 52, and the bearing holder 6dof the primary transfer roller 38d is supported by the fourth step rib 53, respectively in a slidable manner.
Such an abnormality signal detecting section 102b provides a threshold value to the signal intensity of each signal,
and when each signal is outside of the threshold value range, it detects the abnormality of the operating section
49.2
that has generated the signal or the portion in which each of the detecting sections S1 to S3 that has generated
the signal is provided.
The adjustment member is arranged at an outlet port of the air path, branches the air flowing through the air path39.3into a direction toward the conveyance path and a direction toward the developing device, and adjusts volume of
the air that are flowing toward each of the directions.
The circumferential surface of the photosensitive drum 5D is uniformly and positively charged by a charging device
61.7
and is then exposed by the laser scanning unit 60.
